Good article, but shocked to see LiteCoin on top. I don't understand the fascination with litecoin. I have not done well trading it in my experience and feel jinxed by it so I steer clear of it now. I guess it's good tech and all, but I feel like Eth should have ranked above it on this list for "importance" at the current state of affairs.
That said I don't hold either one. I play the little alts myself, and steem steem steem!
furthermore, LTC wasn't at the top by marketcap that time (21 april 2017). A second coin to fly predicted by these guys, interesting
Luck, or genius, who can tell anymore in Crypto, eh my friend?
