Avoid BCash. If we were in regulated markets the people behind BCash would be going to jail for market manipulation and collusion.
Investing in NEO over Gas seems senseless, since you can gain Gas by staking NEO. Waves has the highest potential short-term multiplier, but nobody knows if it will catch on or not right now. Ethereum is the go to for ICOs, at least currently, so it at least shouldn't lose your money (although that is always a possibility).
In general, do your own research and be careful whenever somebody tells you what to do with your money. They're probably trying to exploit your lack of knowledge in one way or another.
Thanks a lot for your advice! There was just a little bit to put on top of the list the Bitcoin Cash because I saw it reached almost $4,000 and I thought if this currency was close to $4,000 once it would be $4,000 and the second time. So NEO can be a good investment. Thank you again for your help!
