No top 10 coin is going to go 30x+, suggestions like Dash or Neo are idiotic. The coins that will do that are very much unkown because they haven't pumped yet, finding them now is like looking for a needle in a haystack while blind folded. So, the best thing is to watch the exchanges for coins that double or triple in value quickly and show strong volume, then buy it for the final 10x+ run. This seems boring, difficult and tedious, because it is. If trading alts was easy everyone would be millionaires and nobody would care about trading alts.
