It doesnt use your smartphone hardware or battery , the mining process is done independent of your phone's performance. Yes I am mining it daily , it just requires a single tap to activate the mining daily. I doesnt even take a minute to be honest. I have around 2500 Pi as of now. Though its not listed in any exchange , I think this coin has potential in future , so we should not miss this opportunity when it is free to mine.I have heard about PI cryptocurrency a lot. I think this crypto token can only be mined using a smartphone as far as I know. Do you really think it is worth mining becuase smartphone hardware is not that good or powerful as compared to expensive computer CPU or GPU. Have you tried mining it personally?
