I am agree with you sir, nowadays even you are going to buy some special hardware miner it still not profitable if you are going to use it to mine bitcoin , you need to find a solar system power to provide cheap electicity than can help you to over power the miner, the passive income for me to earn bitcoin is to do some signature campaign like this.
Yeah me too. Signature campaign is one of the easiest ways to earn some Bitcoin without risking yourself like cloud mining. It is nice income for you while at the same time you learn more about Bitcoin and cryptocurrencies. I'm looking to switch out to solar mining by the way, so in the meantime I will stick with coin staking as it is energy efficient.
