Don't forget about the new player that'll probably play a prominent role in June; LISK. Will be released on the 24th of this month and could explode in value. Supply is more limited compared to Ethereum and demand seems to be pretty high.
But for how long? Most often than not coins that gain a shitton of value within a short period of time
usually go down just as fast. It's a very risky investment which means it's probably avoided by a lot of people.
