Try to invest in the coins/tokens that at their early stage and show good growth dynamics.
If we are talking about currency coins, SkyCoin seems to me quite perspective, it has increased from $13 to almost $40 since December, 2017 and it is based on new 3rd generation ledger - SkyLedger, which eliminates the cost of transaction and transactions goes in seconds.
It is only recommendation and my personal point of view. Anyway you should do your own research and decision based on it.
