There are always new coins and tokens which can make 100x or even 1000x gain. Most of the new ones are scams or will fail quickly though, so you'll need to do a proper research and make the right choice, select wisely which ones of them are worth investing in.
For example, my bet would be DeepOnion if you believe that anonymity / privacy oriented coins will be successfull in 2018. Technologically DO is similar to Verge. But Verge has a market cap of about $2 bil. right now, whereas DO only $60 mil., so huge space to grow.
