As One other analyst has stated, I’m not exactly sure what you mean by ‘best free Bitcoin mining pools’/ The measure of bitcoin- satoshis, normally- that one can earn by playing games, watching ads, etc is small to such an extent that it’s absurd. Basically not worth the exertion, in my view.
In the event that you intended to ask whether there are any mining pools that don't charge for mining costs, I question if there are any. The large miners spend huge amounts of money on cash on new hardware, power, and other overhead costs. Usually, all pools recover a level of their expenses from the mining pool shares that are sold.
I have been bitcoin mining with Bitclub network and I find they have conveyed a remarked exhibition. Happy with the organization and would recommend them to anyone who hasn't considered them as up until this point.
