They are !
It's the core business of Coinbase, Square owns several million in BTC, and Cash App allows the user to buy BTC. Let's imagine if a day cryptocurrencies are totally banned Coinbase will be shut down and the other will lose millions in capital and millions in revenue income.
Yes they have a financial interest, but you do have too, like many others, otherwise, you wouldn't hodl bitcoins and probably wouldn't be here.
Yes but they literally have their lifesavings of investors, their business loans at risk, as well as their career reputations. Unlike many people like me, we only invest what we can lose. So we do hope for a good future but we feel no need to go in and make things happen because we have I guess, belief and utility.
These guys are worried because they're gambling more than what they can afford to lose:) My humble opinion.
