It must be assumed that by this time 17 million bitcoins have already been mined, or it will happen in a matter of hours. However, it can not be said that all 17 million are in circulation. It is estimated that about six million bitcoins have already lost access and this figure will only increase with time.

If all 21 million bitcoins are mined, nothing substantial will happen. Everything will remain the same. Some believe that after this bitcoin will grow in price, as the supply will be limited. This is not true. The market will operate in the same mode and large batches of bitcoins will also be thrown at it periodically.
