I think you should invest in ETH and WAVES as these are two altcoin that will definitely be priced in the future as they both use smart contracts to create new tokens and can develop ICO projects.
Definitely waves doesn't give you a good profit because it have a low volume and we can say the trend of waves is going down. Waves now is something ignore in the market and only few are holding this. It is better to invest coins that are belong to top 10 altcoins in the marketcap, as it have a god market already.
I don't deal with ICO things, they're risky.
I can suggest IOTA, waves, ripple, ethereum classic, litecoin, and tenx. These are the stars of the last days. They give great profits.
