Personally I'm not a fan of BTC or ETH for quite a few reasons, mainly lightening network. I think it;s a horrible scaling solution if you actually look into it. However, I do hold some BTC because I don't see it as being a bad long term investment. It's the name in crypto everyone knows.
It's only a matter of time before we get another nice bull run. I can't wait. Right now I'm stocking up on BTC, ZEN, EOS, ZEC, BTS, and now Steem.
yes diversify is the key. :)
