Let's be honest most alt coins are garbage, other people are just racing to market to release their own coins, they are cut and pasting white papers, get something decent on paper, get a domain, and raise a billion dollars. Funny thing is I made money on TRX, I bought at 3.5 cents, sold at 21.5 cents.
The CEO is a 26 year old guy, who tweets everytime he hires an engineer, everyone seems to be going into the gaming space with their coin, it's a crowded market, with bloated market caps.
Sir Drago predicted XRP to $3 by end of 2017, he was dead on the money with that one. Alt coins have given some amazing returns. It is just getting crowded, and the R word is getting thrown around, so people are taking money off the table. I think ETH has been the big winner for the year. I was hoping BTC would touch on $10K, I believe it has a strong purpose going forward to play in this space, and it has the scarcity clause. I don't think it will be the go to payment coin though for micro transactions.
