I don't believe in doing real Bitcoin mining using mobile device, miners buy expensive equipments and mine Bitcoin offline which is a proof of work ( POS) cryptocurrency. It goes through mining offline in order to mine a certain number the coins. It uses a constant power supply, that's why may countries aren't favourable with the system of Bitcoin mining. They feel it consumes the power supply which could've served many through to the high voltage it consumes. Bitcoin mining can't operate successfully without stand by power supply and mining at a high voltage, which many deemed causing 'environmental hazard, because, it disposes of carbon dioxide into the air during it's mining processing. This kind of activities isn't what we think Mobile Phones can successfully execute, our phone can only do some virtual mining which isn't real mining. Which comes in like a task or tasks we are doing in a particular website, app and the site or app owner gives us commission just for our activities around their platform. Most of those Bitcoin or crypto mining platforms don't even fulfill what they claimed to offer, which is fraudulent and a downtime when it comes to doing virtual mining with the phone.
