If about 4.1 million bitcoins have not moved from their wallets in over five years, there could be several reasons for this. Of course, their owners can expect some very high prices. In addition, unfortunately, access to so many bitcoins has been lost and lost, perhaps forever. Earlier, the possible number of lost bitcoins was indicated - more than six million. This figure should gradually increase.
There is no doubt that interest in the original bitcoin is much higher than interest in its forks.
