Well this is what the insightful Tone Vays claims...
He claims that ETH, DASH, shit 99.5% of all the ALTS are scams and the only coin that will survive is Bitcoin.
So l guess we should all sell our Alts now!
I believe that the altcoins will show good growth after bitcoin, they are in demand on the stock exchange, now you should not sell, even though wait until the market comes out of the drawdown.
