Of course everybody is joining, that is why a lot of exchanges are having to stop registrations and take care of their current customers properly. That is a good sign for business when you have to stop customers from coming in that means there is a massive demand which does not appear to be slowing done any time soon.
Binance just recently enabled registrations again. The thing is that new users don't understand that they can buy a fraction of a
Bitcoin and that the price of the coins doesn't mean anything since the supply differs. This play a big role in pumping coins like
TRON and
Stellar Lumens.
