if in my opinion the price of cryptocurrency that have the opportunity to increase very high (x10 from the current price) is Bitcoin and Ethereum,
It might happen but it should be more than 10 years from now consider when bitcoin reached such ROI and it will worth more than 500k USD. That's quite impossible for bitcoin to reach such rate without done several halving to the its block reward. It's better to bet into the new coins that has great potential.
People didn't need wait for long time to reach such ROI. 10x is very easy when people invested in the right project
