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 would have to say that he is wrong. No one is disputing the fact that a large percentage of the coins that we have in the market right now are scams, but not all of them are scams. There are some that are really good coins which will definitely survive for the long term. The reality is that bitcoin is not enough to serve everyone in the world, we need altcoins.
