No way! Some people says only %10 will survive but i think its in very bad scenario. More likely %40 will survive.
I guess each crypto will survive. Any of the cryptos having good potential and a good volume has the right to survive the markets. Also i am sure that those who are trusting cryptos will always try to be with them and also will try to make a good demand for the cryptos. Almost 60% to 70% coins can survive the market and the rest can be usually Scam which we all are aware about. Future would really be bright for the cryptos and i think that more and more peoples will surely turn towards cryptos ahead so indeed it would go much profitable and in favour of cryptos.
I can't agree with your first statement. Not any crpyto coin will survive and hardly a decent part of them has so-called potential. A lot more of them have nothing behind the beautiful whitepaper. If every coin would survive and have the potential, where are such projects as EGAS, NeoGold, EDT and a lot of them- nowhere.
