thenewgreen this is an answer to your question re institutional investors:
Saylor takes an a extremely narrow view of Bitcoin that does not extend beyond the use of blockchain for anything but a scarce asset. This is the CEO of a company that just raised $650 million from the sale of 0.750% convertible notes to buy BTC.
Personally, I think Bitcoin is long-term unsustainable due to its security fee structure, as well as its environmental impact. I don't think that will prevent it from rallying to $100k and beyond, however.
