In addition to the huge costs of electricity, there is a hidden fee for the simple storage of bitcoins. For each block found, the one who generates the block receives a reward.

For every $ 1,000 bitcoin that it belongs to, a person pays $100 for bitcoin in order to "pay" miners for network security.
