Am new in crypto and seeking cheap and convenient sources of mining coins,What are the less technically complex means to mining that can enable me explore this field,book recommendations would also be very helpful.
Staking coins and mining are they technically the same ? I have come across coins in airdrop that requires one to download a wallet and at the on installing such wallet,it reads waiting for mature coin to start staking...Can one severally stake coins on same device
