If you have a flash drive full of bitcoins and then suddenly, you lose it or it became unusable, the bitcoins in there will be gone forever. Am I right? So, if that's the issue, is it possibe that we run out of supply of bitcoins? If that were to happen, will bitcoin die along with other coins? Or will it die alone?
Currently, about 16 800 000 bitcoins have been mined. Some of them, approximately 6 000 000 with access to them. If access to bitcoin is lost, this, in principle, does not mean that bitcoin has disappeared forever. It remains encrypted in the block chainin block-chain. When the corresponding programs appear, they can be restored. They say that quantum computers will have this ability.
