You can't really predict 5x or 10x in the fews months especially in this bear market. Anyway i can recomend you a good coin with decent chances to rise in price in the next months: Masari.
Reasons: just listed on Crypropia this week, new technology named uncle mining will be released in Q4 2018 and will be unique for this coin, blockchain sharding technology will be release next year with a dedicated whitepaper. If sharding is a success this will bring something new to all CN coins.
