Don't you think that it slowed crypto price rise, since no new users can buy crypto now, an so when new sign ups open again cryptocurrency should moon again?
In fact certain crypto is mooning every now and then, every trader know what it feels like when their promising coins make its promise.
It doesn't slow the crypto price, other users of crypto can still trade their coins in BTC and Altcoin. For an instance in Currency Exchange.
I mean, currently it's very hard to "enter crypto world" if you don't have any crypto already.
