Yes, the most important thing is that larger business start using BTC. That is happening, and it will happen more and more. As we see it for now, that path is just moving forward, atleast since 2017-18. It is almost impossible anyone who entered btc world will leave it.
Some businesses started using bitcoin because of the hype... Agree that buying a Tesla for bitcoin, paying a $10-20 commission, or a cup of coffee, with the same commission, are two huge differences!
