Just a heads up, crypto miners for mobile phones are a scam, ESPECIALLY if they say they mine coins like Shib. Shib is not coded onto a block chain. It sits in a wallet that you can buy shib out of. You can't mine shibcoin. You CAN mine bitcoin and ethereum, but definitely can't mine alt coins. But using a phone won't get you any real results anyways. You need to use a gpu system to get any results, which will cost you a pretty penny as well as more on your electric bill.
