If you're going for max profit with well... max risk, you can always jump on a coin when it's new and hope it starts being traded. Even jokecoins have a trading value for some reason (see memecoin).
To be honest, if you aren't going to be actively watching the market and sell the coins at good moments while profit mining, stick to Litecoin.
i hear memecoin get 750 gbp month on 190kh/s is true?
