Managed well which cryptocurrency you would like to mine don't calculate just for today, your return of income will depend on the price of the coin that you wanted to mine so look for a coin that you think will increase soon in order to recover your investment to your equipment also don't forget the electricity consumption for the time you have started mining.

The most profitable coin I think is the new coin since the difficulty is low but the risk is the coin might not be valuable for a long term so carefully pick a new good coin to mine.

You can mine ETH for now and hold it and wait for the ETH's value to increase.
