I'm also the same in that I'm not invested in any of them except Ethereum, and I did so without really knowing too much about it, lol. Now I've been doing more research and I think both EOS and NEO have potential. All three of these seem similar in the sense that they do smart contracts. I like that NEO is heavily used in China. EOS seems to have the most scalability out of the three in that it can take on more transaction volume. I think they're all worth keeping an eye on.
