I have a mixed feeling about this.
Micheal Saylor is obviously very smart, and a very good orator. But the tone that he uses on some occasion I guess sounds too extreme when speaking to a bank.
“Sell your house and buy Bitcoin” is not a financial advice, of course, but I am not sure is something a bank want to be coupled with.
Central banks of various countries are using Bitcoin as a transaction and as a holding. This is definitely a positive aspect for Bitcoin, because if central banks support Bitcoin, the people of that country will be attracted to Bitcoin holding. Various officials including the government will also be involved in this Bitcoin holding, they will grasp Bitcoin more.
