Good Day!
For me, when you are a miner, miners are becoming the main consumers of energy in the growing bitcoin ecosystem,it consumes lot of energy, we all know that once there are too much electricity you burn, and the faster your computer, the higher the chances of  coins that can be assigned to the owners of the machines., in short you'll gonna have a chance to win the competition. Bitcoin mining is a competition to waste the most electricity possible by doing pointless arithmetic quintillions of times a second. That's how it works. So no wonder why it consumes a lot of energy or power.
Besides, these will happen only that it use a lot a of power when the popularity of currency likely to happen or increases.

To sustain this project and in order to have a good pathway in earning money in a fast and easy way we need function.
