Canaan's IPO Lockup Period Ends

IPO's are for investors to exit, not for new capital right?

Happy 20-days A.H. (After-Halving) everyone.

While painful for miners, the halving really sparked a lot of interest in mining from the outside community. FTX’s Difficulty Futures have $100k in daily volume & more people are starting to watch the market.

We are following the hashrate levels (and difficulty) quite closely. The S19 and M30S shipping, Sichuan rainy season, firmware penetration are all macro events that are extremely important for miners and for traders looking to enter the space.

This update we also cover the latest mining news on Bitfury, Iran, Canaan, Coinmint, Coin Metrics, Bitmain and more.

If you like this newsletter we would be grateful for you to share it with your friends & colleagues.

Product Feature

We launched Catalyst in September 2019 with the simple realization that alt-coin miners want Bitcoin, so why not pay them in it.

As an PPS mining pool, we are just purchasing hashrate. Historically we did so in the native token that we were mining. But given miners need to pay off electricity and opex bills we figured why not make it easier for them by paying in Bitcoin.

In the future, we hope to offer a feature that allows miners to be paid for their hashrate in a mix of Bitcoin, USD or stablecoin.


Trading Update


  1. Bitcoin transaction fees have fallen from ~$2mm a day post-halving to ~$700k/day. This put some downward pressure on SHA-256 hashprice. Network difficulty is expected to drop ~9% on Thursday so expect hashprice to rebound slightly. If coupled with positive price movement we could see hashprice recover to above 10 cents a TH.
  2. The S19 and M30S are being shipped. After all the issues with the S17, Bitmain will be looking to bounce back as the preferred manufacturer. The S19s are beating Whatsminer on price ($/TH) and also on efficiency (J/TH). All of that means nothing if the machines are breaking.
  3. Canaan’s 180-day IPO lockup period has expired, which means that some pre-IPO investors can now sell their shares on the open market. It is hard to say what impact this had on stock price but Canaan is down 61% since our last newsletter. Q1 earnings and the ongoing lawsuit didn’t help.

Mining News

A few updates from the past couple of weeks in the mining industry:

  • Bitfury announced a new investment vehicle for accredited investors. Targeting family offices, Bitfury hopes to provide investors with alternative exposure to Bitcoin. In the investment page, it says that their mining equipment is being deployed at 38 J/TH and better. However, it is unclear if this efficiency is measured when in immersion cooling. The once-dominant ASIC manufacturer has lost a lot of momentum as their products have not been able to keep up with Bitmain and Whatsminer. (article)
  • Iran has begun working on a national strategy for crypto mining. By regulating the industry they can prevent private individuals from escaping capital controls, can generate income for the State, and use the proceeds to help them get around sanctions laws. I suspect the government to jump into mining directly or in JV structures. (article)
  • Coin Metrics was able to use a novel nonce distribution analysis of Bitcoin to numerically estimate the amount of hashpower provided by certain types of hardware. Using this they determined the amount of S9s and S17s on the network. (article)
  • It was circulating on social media that regulators in Sichuan issued a notice to all crypto-businesses to end mining activity. (article) This is a clear example of a time where there is a disconnect between the East and West. Mining in Sichuan is not ending, the farms have relationships with local governments there and are continuing to expand. A few days ago there was a large & public mining conference in Chengdu (Top Hash).
  • On the topic of Sichuan, the rainy season just kicked in. Starting in May, there is more rain in this region, leading to surplus hydroelectricity and a reduction in electricity prices. This year, all-in hosting prices are 5-10% cheaper than last year (around $0.03 - $0.033). (tweet)
  • The internal battle rages on in Coinmint, the largest mining company in North America. On May 19th the court got involved. (court case) Coinmint is an important part of the North American mining ecosystem, so I’m hoping that things are resolved soon.
  • Bitmain released its latest T19 last night, which sold out in less than an hour. 84TH/s & 37.5 J/TH for $1,749. (website)

Know the difference between FPPS, PPS+ and PPLNS payment methods?

We walk over the exact differences and why we think FPPS is the most robust payment method. Which is why we also recently switched our Bitcoin pool from PPS+ to FPPS.
