With budget like yours keep eyes on coins|tokens which are out of top-100 market cap and launched not long ago. Okay, you might invest to IOTA and maybe EOS from mainstream coins.
But to get 10-100x you should for for something like SONM, Genesis Vision. Also invest some dollars for Sagacoin. This coin can do a 100x.
Iota, neo are my choice for this low budget investment. Yes sonm is also good its future price is profitable. I never check the sagacoin if it is good but I will look into this coin.
