Re: Bitcoins and other cryptos will never become mainstream before...
I'd bet 10 years from now, BTC would've already solved its scaling issues without sacrificing decentralization. The future is not set, so anything's possible.
It's already been more than 10 years. And billions of dollars have been poured into the problem. And Bitcoin is slower and more expensive now than it's ever been.
I'm betting the other way, personally.
