What is cryptocurrency and how it is generated?

Answer 1

crypto is a virtual currency that you can gain by using your computers processors gpu/cpu to calculate blockchain or by processing largely time&resource consuming calculations.
So you basically turn your electricity bill larger by creating a volatile viritual currency which you don't even legally own just to make a some profit.
I wouldnt get into the business unless you are ready to lose money and without any business understanding or proper hardware and electricity pricing to "mine" profitably
