I do not know because the amount of altcoin is so much and it will take a long time to doing research to compare altcoin one with another altcoin. But for me, certainly convinced altcoin at the top is highly potential for an investment. Well, this is just my suggestion because I have invested in this altcoin which I think is very potential, that's ethereum and NEO. I Just suggestion, if you have more time to doing research on altcoin, Ethereum and NEO you should be consider.
