I feel like recommendation across all board for OmiseGO, Monero and NEO is still very strong. Personally for me would be ETH . There's a lot of other variations to consider too, eg; the duration to HODL (5 and 10 years are quite the difference).
The current time is bitcoin only because its value is going increasing step by step and we can also understand well that we have chance to make much money with the free amount of bitcoin gold ( BTG ) in front of same amount of bitcoin that we will have will get And Blockchain and Platform Ethereum used by many project that cause the demand continue increasing .
