Take a look at following altcoins if you address to be a cryptomillionaire in 2-3 years and thank me later:
- NEO (former Antshares) - the chinese ethereum with a nice future
- Verge (XVG) - the only and true absolutely anonymous coin with RSK (smart contracts) following end of July/begin of August
- Stratis (STRAT) - very nice tech with a solid dev team
- OmiseGO (OMG) - wait for Q4 to see this nice project in action, already in work with McDonalds Thailand
- Ark - wait for smart bridge implementation to see this coin changing the whole cryptoworld
Just my 2 cents.
