Which strategy would make me the most money in one month's time?
I guess earn money consistantly.

There is no certain coin that will make you money on low hashpower when mined. The only thing you can do is solo mine a coin that launched within the past few days and hope that it actually turns to something in the future after you accumulate some.
Alternatively you can mine any of the popular ones (Bitcoin, Ethereum, Monero) and hope that you find a block.
It's a gamble nevertheless.
