Try coins that are decentralized, that have active developers, that are different than bitcoin and that are somehow useful.
Try Siacoin, or Monero, Litecoin also has a future.
I own BTC, just a bit of ETH, ETC, Sia, Expanse, Musicoin(I just like the name of this one
), XMR, DCR(mined recently), Litecoin (purchased a few yesterday).
