i would recommmend you to split the whole amount into 4 peaces. so you can put 2,5k in each coin (2 stable coins, 2 others) i think ethereum and bitcoin is a must have and this should be the two stable ones. than i would pick iota and waves, because the price is very low right now and i see high potential. but this is just my own opinion and i also want to say that i'm still investet in all of them.
