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!
Anyone can say bad or good about cryptocurrencies in general and that's for free. That's the OP's opinion towards bitcoin and altcoins. But for me, my opinion is completely the opposite to his/her opinion. If all altcoins are scam, then how come they still exist today and earn profit from them?
