Sam Tabar is the CEO of BitDigital, and they mined BTC for years. They are still mining but have pivoted toward ETH. They said they will continue mining BTC until it is no longer profitable, at which point they'll shut down the machines—after which they’ll essentially become paperweights. He had a meeting with Michael Saylor who told him BTC mining is a shit business and that he should just buy BTC instead. He told Saylor he agreed with him, but that he will buy ETH instead. Saylor gave him a dirty look and the meeting went south after that. 
He talks about it in this video.
Good video! Some interesting points:
- Saylor mentioned bitcoin mining is a 'shit business.'
- Tabar agrees, difficult to make a profit, could see more bitcoin mining pivoting to ETH or closing down.
- Saylor holding 2-3% of Bitcoin.
- This poses a 'giant key man risk.'
- ETH Strategic Reserve is at least split between many competing players and ownership is far less centralised.
- Saylor telling Tabar 'ETH is going to zero' shows he's just a regular delusional maxi.
On a side note, Saylor was also one of those claiming 'ETH is a security' and siding with Gensler in his witch hunt against Ethereum and Consensys.
Joe Lubin has mentioned in several interviews that they were 'advised' to keep quiet which is why the Ethereum Foundation, Consenys and other ETH projects had to be punching bags for the past few years as they were unable to defend themselves.
Lubin also said the Biden administration were actively trying to destroy Ethereum and defi, and they were facing constant harassment from the SEC. Even receiving a subpoena. He says regular ETH developers were worried about receiving subpoenas!
Gensler and the SEC under his watch did a HUGE amount of damage to Ethereum, which is now having to play catch-up for several lost years.
