The current market volume for altcoins and btc is insane compared to a few months ago, where did it al go??? it was probably never real in the first place.
The hype ended. It will not come back before Bitcoin reach old ATH, so $20000 again. Bitcoin, Monero and all crypto will be way stronger and ready when that happens. It will again happen that exchanges will have no support anymore although doubled their employed in last few months. And it will happen again that exchanges closed registrations although there will be 10 times more exchanges as was in 2017. But it will take some time for that to happen.
