Since I am fairly new to crypto my best investement right now is OmiseGo but Antshares(NEO) and IOTA are doing pretty good as well.
That's pretty fortunate of you. Those coins have been BOOMING.
I'm still new myself but I consider the little bit I put into BTC a couple weeks ago a pretty big success. I've made more bad moves than good ones so far (sold some BTC on 7/31, sold some XRP and bought some altcoins which went down thereafter, along with XRP but to a bit higher degree). I'm not really a trader though but more of a hodler.
