There are currently around 32 million bitcoin wallets. The last thing we should be worried about is the amount of people in the space right now. Specially considering a lot of those wallets are the second or third of a singular person. If crypto is to be as big as most of us see it there are at least a billion more users yet to come. And even if that number ends up at a hundred million that would cause a bull market that would eclipse 2017 December into oblivion.
