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!
Nobody is in it just for the tech. In fact, despite their claims, most don't really understand the tech beyond a few misguided regurgitations of clueless summaries. They just say that because it makes them feel a little better even as the thing is going to the dogs. Much better to say "I don't care; I'm in it for the tech" than to say "I'm a dummy, and I'm getting fucked".
