I don't think it is realistically possible to predict a single cryptocurrency that will increase x100 within the next year. The most likely scenario I see that happening is an ERC-20 ethereum token going from around $0.01 USD to around $1.0 USD.
You can view the prices of ERC-20 tokens listed on https://etherscan.io/tokens. Maybe finding a few of the cheap ones might be a start. Research the tokens and try to determine which ones look promising. Some of them are even fractions of a penny.
Of course, only invest what you can afford to lose.
