Mining for Profitability - Horizen (formerly ZenCash) Thanks Early GPU Miners

Mining for Profitability - Horizen (formerly ZenCash) Thanks Early GPU Miners
Thank you for inviting Horizen to the GPU mining AMA!
ZEN had a great run of GPU mining that lasted well over a year, and brought lots of value to the early Zclassic miners. It is mined using Equihash protocol, and there have been ASIC miners available for the algorithm since about June of 2018. GPU mining is not really profitable for Horizen at this point in time.
We’ve got a lot of miners in the Horizen community, and many GPU miners also buy ASIC miners. Happy to talk about algorithm changes, security, and any other aspect of mining in the questions below. There are also links to the Horizen website, blog post, etc. below.
So, if I’m not here to ask you to mine, hold, and love ZEN, what can I offer? Notes on some of the lessons I’ve learned about maximizing mining profitability. An update on Horizen - there is life after moving on from GPU mining. As well as answering your questions during the next 7 days.

Mining for Profitability - Horizen (formerly ZenCash) Thanks Early GPU Miners

Author: Rolf Versluis - co-founder of Horizen

In GPU mining, just like in many of the activities involved with Bitcoin and cryptocurrencies, there is both a cycle and a progression. The Bitcoin price cycle is fairly steady, and by creating a personal handbook of actions to take during the cycle, GPU miners can maximize their profitability.
Maximizing profitability isn't the only aspect of GPU mining that is important, of course, but it is helpful to be able to invest in new hardware, and be able to have enough time to spend on building and maintaining the GPU miners. If it was a constant process that also involved losing money, then it wouldn't be as much fun.

Technology Progression

For a given mining algorithm, there is definitely a technology progression. We can look back on the technology that was used to mine Bitcoin and see how it first started off as Central Processing Unit (CPU) mining, then it moved to Graphical Processing Unit (GPU) mining, then Field Programmable Gate Array (FPGA), and then Application Specific Integrated Circuit (ASIC).
Throughout this evolution we have witnessed a variety of unsavory business practices that unfortunately still happen on occasion, like ASIC Miner manufacturers taking pre-orders 6 months in advance, GPU manufacturers creating commercial cards for large farms that are difficult for retail customers to secure and ASIC Miner manufacturers mining on gear for months before making it available for sale.
When a new crypto-currency is created, in many cases a new mining algorithm is created also. This is important, because if an existing algorithm was used, the coin would be open to a 51% attack from day one, and may not even be able to build a valid blockchain.
Because there's such a focus on profitable software, developers for GPU mining applications are usually able to write a mining application fairly rapidly, then iterate it to the limit of current GPU technology. If it looks like a promising new cryptocurrency, FPGA stream developers and ASIC Hardware Developers start working on their designs at the same time.
The people who create the hashing algorithms run by the miners are usually not very familiar with the design capabilities of Hardware manufacturers. Building application-specific semiconductors is an industry that's almost 60 years old now, and FPGA’s have been around for almost 35 years. This is an industry that has very experienced engineers using advanced design and modeling tools.
Promising cryptocurrencies are usually ones that are deploying new technology, or going after a big market, and who have at least a team of talented software developers. In the best case, the project has a full-stack business team involving development, project management, systems administration, marketing, sales, and leadership. This is the type of project that attracts early investment from the market, which will drive the price of the coin up significantly in the first year.
For any cryptocurrency that's a worthwhile investment of time, money, and electricity for the hashing, there will be a ASIC miners developed for it. Instead of fighting this technology progression, GPU miners may be better off recognizing it as inevitable, and taking advantage of the cryptocurrency cycle to maximize GPU mining profitability instead.

Cryptocurrency Price Cycle

For quality crypto projects, in addition to the one-way technology progression of CPU -> GPU -> FPGA -> ASIC, there is an upward price progression. More importantly, there is a cryptocurrency price cycle that oscillates around an overall upgrade price progression. Plotted against time, a cycle with an upward progressions looks like a sine wave with an ever increasing average value, which is what we see so far with the Bitcoin price.

Cryptocurrency price cycle and progression for miners
This means mining promising new cryptocurrencies with GPU miners, holding them as the price rises, and being ready to sell a significant portion in the first year. Just about every cryptocurrency is going to have a sharp price rise at some point, whether through institutional investor interest or by being the target of a pump-and-dump operation. It’s especially likely in the first year, while the supply is low and there is not much trading volume or liquidity on exchanges.
Miners need to operate in the world of government money, as well as cryptocurrency. The people who run mining businesses at some point have to start selling their mining proceeds to pay the bills, and to buy new equipment as the existing equipment becomes obsolete. Working to maximize profitability means more than just mining new cryptocurrencies, it also means learning when to sell and how to manage money.

Managing Cash for Miners

The worst thing that can happen to a business is to run out of cash. When that happens, the business usually shuts down and goes into bankruptcy. Sometimes an investor comes in and picks up the pieces, but at the point the former owners become employees.
There are two sides to managing cash - one is earning it, the other is spending it, and the cryptocurrency price cycle can tell the GPU miner when it is the best time to do certain things. A market top and bottom is easy to recognize in hindsight, and harder to see when in the middle of it. Even if a miner is able to recognize the tops and bottoms, it is difficult to act when there is so much hype and positivity at the top of the cycle, and so much gloom and doom at the bottom.
A decent rule of thumb for the last few cycles appears to be that at the top and bottom of the cycle BTC is 10x as expensive compared to USD as the last cycle. Newer crypto projects tend to have bigger price swings than Bitcoin, and during the rising of the pricing cycle there is the possibility that an altcoin will have a rise to 100x its starting price.
Taking profits from selling altcoins during the rise is important, but so is maintaining a reserve. In order to catch a 100x move, it may be worth the risk to put some of the altcoin on an exchange and set a very high limit order. For the larger cryptocurrencies like Bitcoin it is important to set trailing sell stops on the way up, and to not buy back in for at least a month if a sell stop gets triggered. Being able to read price charts, see support and resistance areas for price, and knowing how to set sell orders are an important part of mining profitability.

Actions to Take During the Cycle

As the cycle starts to rise from the bottom, this is a good time to buy mining hardware - it will be inexpensive. Also to mine and buy altcoins, which are usually the first to see a price rise, and will have larger price increases than Bitcoin.
On the rise of the cycle, this is a good time to see which altcoins are doing well from a project fundamentals standpoint, and which ones look like they are undergoing accumulation from investors.
Halfway through the rise of the cycle is the time to start selling altcoins for the larger project cryptos like Bitcoin. Miners will miss some of the profit at the top of the cycle, but will not run out of cash by doing this. This is also the time to stop buying mining hardware. Don’t worry, you’ll be able to pick up that same hardware used for a fraction of the price at the next bottom.
As the price nears the top of the cycle, sell enough Bitcoin and other cryptocurrencies to meet the following projected costs:
  • Mining electricity costs for the next 12 months
  • Planned investment into new miners for the next cycle
  • Additional funds needed for things like supporting a family or buying a Lambo
  • Taxes on all the capital gains from the sale of cryptocurrencies
It may be worth selling 70-90% of crypto holdings, maintaining a reserve in case there is second upward move caused by government bankruptcies. But selling a large part of the crypto is helpful to maintaining profitability and having enough cash reserves to make it through the bottom part of the next cycle.
As the cycle has peaked and starts to decline, this is a good time to start investing in mining facilities and other infrastructure, brush up on trading skills, count your winnings, and take some vacation.
At the bottom of the cycle, it is time to start buying both used and new mining equipment. The bottom can be hard to recognize.
If you can continue to mine all the way through bottom part of the cryptocurrency pricing cycle, paying with the funds sold near the top, you will have a profitable and enjoyable cryptocurrency mining business. Any cryptocurrency you are able to hold onto will benefit from the price progression in the next higher cycle phase.

An Update on Horizen - formerly ZenCash

The team at Horizen recognizes the important part that GPU miners played in the early success of Zclassic and ZenCash, and there is always a welcoming attitude to any of ZEN miners, past and present. About 1 year after ZenCash launched, ASIC miners became available for the Equihash algorithm. Looking at a chart of mining difficulty over time shows when it was time for GPU miners to move to mining other cryptocurrencies.

Horizen Historical Block Difficulty Graph
Looking at the hashrate chart, it is straightforward to see that ASIC miners were deployed starting June 2018. It appears that there was a jump in mining hashrate in October of 2017. This may have been larger GPU farms switching over to mine Horizen, FPGA’s on the network, or early version of Equihash ASIC miners that were kept private.
The team understands the importance of the cryptocurrency price cycle as it affects the funds from the Horizen treasury and the investments that can be made. 20% of each block mined is sent to the Horizen non-profit foundation for use to improve the project. Just like miners have to manage money, the team has to decide whether to spend funds when the price is high or convert it to another form in preparation for the bottom part of the cycle.
During the rise and upper part of the last price cycle Horizen was working hard to maximize the value of the project through many different ways, including spending on research and development, project management, marketing, business development with exchanges and merchants, and working to create adoption in all the countries of the world.
During the lower half of the cycle Horizen has reduced the team to the essentials, and worked to build a base of users, relationships with investors, exchanges, and merchants, and continue to develop the higher priority software projects. Lower priority software development, going to trade shows, and paying for business partnerships like exchanges and applications have all been completely stopped.
Miners are still a very important part of the Horizen ecosystem, earning 60% of the block reward. 20% goes to node operators, with 20% to the foundation. In the summer of 2018 the consensus algorithm was modified slightly to make it much more difficult for any group of miners to perform a 51% attack on Horizen. This has so far proven effective.
The team is strong, we provide monthly updates on a YouTube live stream on the first Wednesday of each month where all questions asked during the stream are addressed, and our marketing team works to develop awareness of Horizen worldwide. New wallet software was released recently, and it is the foundation application for people to use and manage their ZEN going forward.
Horizen is a Proof of Work cryptocurrency, and there is no plan to change that by the current development team. If there is a security or centralization concern, there may be change to the algorithm, but that appears unlikely at this time, as the hidden chain mining penalty looks like it is effective in stopping 51% attacks.
During 2019 and 2020 the Horizen team plans to release many new software updates:
  • Sidechains modification to main software
  • Sidechain Software Development Kit
  • Governance and Treasury application running on a sidechain
  • Node tracking and payments running on a sidechain
  • Conversion from blockchain to a Proof of Work BlockDAG using Equihash mining algorithm
After these updates are working well, the team will work to transition Horizen over to a governance model where major decisions and the allocation of treasury funds are done through a form of democratic voting. At this point all the software developed by Horizen is expected to be open source.
When the governance is transitioned, the project should be as decentralized as possible. The goal of decentralization is to enable resilience and preventing the capture of the project by regulators, government, criminal organizations, large corporations, or a small group of individuals.
Everyone involved with Horizen can be proud of what we have accomplished together so far. Miners who were there for the early mining and growth of the project played a large part in securing the network, evangelizing to new community members, and helping to create liquidity on new exchanges. Miners are still a very important part of the project and community. Together we can look forward to achieving many new goals in the future.

Why I see Virtcoin as a $200 coin when really considering ASIC resistance

First of all, Vertcoin does indeed have a tremendous community, and this is not to be understated. However, this is only a fraction of the value position of this coin. I just want to expand on the ASIC resistance thing a bit. As an electrical engineer who has actually designed ASIC's, I do have some background on this. What I can tell you is that this term "ASIC Resistant" is that it is a little bit misleading. In theory, any algorithm can be turned into an ASIC. An ASIC or Application Specific Integrated Circuit is a digital or analog or mixed analog digital circuit that has been cast into Sea of Gates, Semi-Custom, or Full Custom ASIC technology. The cheapest route is Sea of Gates. If one didn't want to do a Sea of Gates ASIC, they could implement an algorithm in a FPGA, or Field Programmable Gate Array. Altera and Xilinx are the dominant players here. In the early days of Bitcoin, there were many FPGA miners, this was a very common way to mine Bitcoin.
Overall, It takes somewhere between USD $50,000 to $1,000,000 to make an ASIC. It's an expensive process. There is a tremendous amount of engineering, where the circuit is designed in System Verilog, Verilog or VHDL, and very extensive testbenches to make sure that the when the chip is made it works the first time. Engineers prototype ASICs in FPGA's, and the development boards for ASIC emulation can cost $20k or more just in themselves. Then the design goes to a foundry where the chip is made, and that will be expensive, $50k to $500k. So there has to be motivation to make an ASIC, such as high volume chip sales. For Sea of Gates technology, a rule of thumb is that there is typically a break even point when a company sells 1,000 to 2,000 chips a year that has been made into an ASIC. That is because Sea of Gates is about a $100k process.
The ASIC Resistance of Vertcoin is not technology related, i.e. the algorithm that is currently being used could be made into an ASIC. What makes Vertcoin ASIC resistance is the commitment of the team to change the algorithm if someone does make an ASIC to mine Vertcoin. This is what gives Vertcoin it's value position. I really appreciate that! This is a de-facto way to limit the power of miners, in one simple swipe.
How wants to deal with this Bitcoin forking situation anymore? At this point, with the upcoming fork, it seems more and more unnecessary. I see Bitcoin as a storage of value layer, and other coins such as VTC and LTC as transaction layer coins.
To me what gives VTC value is the intention of the community AND the consequent action of it.

Need of FPGA  Field Programmable Gate Arrays  VLSI Design Implementation of UDP Protocol using FPGAs HeteroRefactor: Refactoring for Heterogeneous Computing with FPGA MachXO2 Speed Seminar - Module 1 Overview Hugo de Garis - Against Nationalism - Humanity+ @Melbourne

In the last few years, the crypto mining jumped from one ship to another, mostly from GPU mining to ASICs and then back to GPU mining. However, there is another recent option for miners to choose, called FPGA mining. FPGA or Field Programmable Gate Array is a highly adaptable microchip that offers miners low-cost alternative of expensive GPUs. By June 2011, mining via Field Programmable Gate Arrays (FPGAs) were preferred over GPU mining rigs, as their electricity consumption was comparably lower [8]. Mining bitcoin via FPGAs lasted no Built around the revolutionary Field Programmable Gate Array or FPGA technology, these miners can deliver exceptionally high hash rate without consuming a lot of power. Both the multi-algorithm miners from BitHull can be used for mining Bitcoin, Litecoin, Ethereum, and Monero. Dublin, May 11, 2020 (GLOBE NEWSWIRE) -- The "Field Programmable Gate Array Market Size, Share & Trends Analysis Report by Technology (SRAM, Antifuse, Flash), by Application (Military & Aerospace, Telecom), by Region, and Segment Forecasts, 2020 - 2027" report has been added to ResearchAndMarkets.com The next leap for bitcoin mining came with the Field Programmable Gate Array (FPGA). They can be programmed and customized by the end-user. Big time mining outfits loved FPGAs for its flexibility. More importantly, FPGAs were many, many times faster than the best GPU in the market.
