This article is to function nothing greater than a contribution to the bitcoin mining group.
I’m not a mathematician.
I’m not a statistician nor an authorized economist.
I’m only a bitcoin miner, a builder, and a freethinker that loves spreadsheets and algebra and, for the final 4 years, I’ve been making an attempt to determine a technique to correctly worth bitcoin ASICs at any given time whereas considering total market situations.
The following is the advanced calculation I’ve used to find out whether or not or not I ought to pull the set off and buy an ASIC — or somewhat it is a calculation that helps me from changing into overzealous and overpaying for {hardware}. I’ve been impressed to share this by the outstanding of us in DBF.
It has saved me from making errors, hopefully you discover it to be helpful.
Denver’s Derivative Explained
Some phrases to outline:
- Watts/Th = An ASIC’s whole watt consumption divided by its nominal Th/s score.
- $/Th = The whole price of an ASIC divided by its nominal Th/s score.
- WattDollar = The product of an ASIC’s watts/Th multiplied by $/Th.
- Hash value = USD worth of 1 Th/s over the course of 24 hours.
- Elongated hash value = USD worth of 1 Th/s over the course of 50,000 blocks.
Denver’s Derivative (DD) = WattDollar/Elongated hash value =
- >50 = If your energy is lower than ~$0.035 OR you’re going to run the ASIC for five-plus years.
- <50 = If your energy is lower than ~$0.055 OR you’re going to run the ASIC for four-plus years.
- <40 = If your energy is lower than ~$0.075 OR you’re going to run the ASIC for three-plus years.
- <30 = If your energy is lower than ~$0.125 OR you’re going to run the ASIC for 3 years.
- <20 = If your energy is lower than ~$0.15 OR you’re going to run the ASIC for two-plus years.
- <15 = Borrow to purchase all of the {hardware} (simply kidding however probably not).
Below is a screenshot of some present bitcoin ASIC fashions, their respective specs and their DD score:
Keep in thoughts these calculations had been based mostly on the present hash value of $0.275 and, subsequently, an elongated hash value of $95.48 on the time I wrote this text per the Slush Pool/Braiins dashboard:
The Problem
The drawback as we speak is that ASICs are priced based mostly extra on bitcoin’s market value than on profitability of the ASICs.
While which may sound like the identical factor and, sure, bitcoin’s value undoubtedly performs a task as as to whether or not an ASIC is worthwhile — but it surely’s not the solely variable — whole community competitors must even be taken into consideration. This is why the hash value is vital — the hash value takes into consideration the worth of a single Th/s over the course of 24 hours — this accounts for whole competitors/issue on the community. Therefore, ASICs must be priced based mostly upon hash price, however as a substitute they’re seemingly priced solely on bitcoin’s market value and sentiment round that market value.
A fast instance of how this creates disequilibrium all through {hardware} markets:
Let’s say as we speak an Antminer S19 is priced at $10,000 even and bitcoin’s market value is at $50,000 even. In as we speak’s market, what we see is that if bitcoin’s market value strikes to $55,000 (a 10% improve), we’ll typically see a comparable relative improve in ASIC costs, and that $10,000 ASIC is now $11,000 delivered. But that ASIC will not be 10% extra worthwhile denominated in USD. Here’s why: If, whereas the bitcoin value elevated from $50,000 to $55,000, the whole competitors on the community might have elevated from 160 Eh/s to 168 Eh/s (5% improve). So sure, the bitcoin that the identical ASIC is incomes is now price 10% extra, nevertheless, it’s also incomes 5% much less bitcoin than it was earlier than, so actually that ASIC is possibly solely 5% extra worthwhile, but it surely’s now 10% dearer. I wished to quantify that alpha to attempt to keep away from overpaying for {hardware}, whereas having the ability to reap the benefits of value dips in {hardware} price relative to profitability (a uncommon incidence).
This is why incorporating the elongated hash value variable was vital: It allowed me to tether the worth and effectivity of ASICs to the truth of how worthwhile bitcoin mining is “in general” (or how priceless a Th/s is, usually) at any given time.
This actuality is indicative of an immature market ripe for disruption, innovation and commoditization. I hope to see maturation within the coming 9 years, however within the quick time period, I’ll be relying upon this by-product to know whether or not or not my ASIC value is on par with historic costs.
Conclusion
The motive I personally discover this calculation to be helpful is as a result of it takes into consideration the three most vital variables when buying an ASIC:
- The thermodynamic/computational effectivity of the ASIC — w/Th
- The capital/price effectivity of the asic — $/Th
- The total well being of the hash energy market — elongated hash value
This manner I might inform if I used to be getting value throughout time.
This manner I might assist those that wish to mine at dwelling utilizing Upstream Data’s BlackBox.
I hope you discover it to be helpful and I welcome any and all criticism.
May you discover nice success in all of your hashing endeavors.
