Mining Rig Rental -MRR says daily returns is 11$ but popular website like whattomine shows 7.5$ per day and Nicehash shows 8.9$ per day, I think I will go with either Nicehash pool or MRR pool.

@Charles-Tim 50% of my electricity fee per day is free because I have solar panels installed, mining from 9am to 6pm is 100 percent guaranteed, the rest will be on grid power.

I have good power bank too but with the power consumption of an s19 pro the bank up will only last me up to 4 hours.
