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!
maybe it's true maybe not, because altcoins are very easy to create, but what makes them grow is the projects they run and are useful for many people, so only a few altcoins are scam, just making altcoins without making them like fake projects
