I still buy Nano, Litecoin, Electroneum and DGB and have also some non top 100 coins but i really don't want know to write here because maybe they not have a chance to grow.
I'm pretty sure that nano, eltetroneum and digibyte are old and dead coins and people have lost interest on it except litecoin. You should buy new coins like those that are launch in Binance by using the IEO success and one of them is the Harmony One and you just don't know it yet but the hype on this one is big.
