I have thought about this before when I newly came into the crypto market, if someone can mine there BTC using their smart phone.
After reaching out to cryptocurrency miners and i also carry out my own research about it, I came to understand that you can mine your BTC using your smart phone, but it's not practical base on it negative effects.
Mining your BTC on your smart phone we significantly impact to your phone battery life and energy consumption, and it we earn no rewards due to low processing power of the device, and can also damage your device and many more.
Please I we really be grateful if the miners here we troll more light on what I just said for more clarity.
