A friend asked, how many bitcoins are irretrievable?
To be honest, no one can give a precise number, but we can try to estimate. We can categorize the currently circulating bitcoins by their 'birth' dates, which actually refer to the creation time of UTXOs.
Let's take a look at the bitcoins 'born' between 2010 and 2014; they peaked in number in December 2014, and then started to decrease rapidly. By January 2019, there had basically been no significant changes.
These old bitcoins that haven't moved until now, aside from some die-hard fans who still hold onto them, I guess most of them must have been lost. I think the proportion of lost bitcoins must be at least half, which means at least over 1,060,000 coins.
Even more impressive, there is a batch of bitcoins that were 'born' in 2009, which haven't moved much since December 2011. To this day, this address group still holds 1,087,371 bitcoins!
I am curious, who is this person, so amazing, with so many bitcoins!
Big things are coming! A divine order is about to be announced! The car is too heavy to move! After careful consideration, I still choose to share in the chat room! If you want to get on the highway, you can Ca11 me!
