Ethereum has really risen since last year, astronomically at that. I do, however, still think that Bitcoin will continue to dominate the cryptocurrency space, even with Bitcoin Cash threatening to take it over.
In the same breath, the crypto space is really unpredictable and it is very interesting as to which coin/platform will dominate in a few years to come. Maybe it's not even created yet. Who knows? Here's what I do know though, I'm holding most of my Alts, including Btc of course. The future looks bright and most of these will sky rocket come next year
