Although price of whole crypto market is really low but I don't think it'll affect to sustainability of cryptocurrency. This is not the first time crypto world has to face to crisis like this but crypto world still can alive and develop until now. I think this time it'll affect to much and maybe at the end of this year everything will be better although just a little bit.
I hope so...
And in my opinion, if crypto can accross this situation and out from this into the next bull run,this will prove the power of crypto and will make a very big effect
