This is fascinating — almost half of all bitcoins will eventually become lost or unrecoverable:
“According to new research from Chainalysis, a digital forensics firm that studies the bitcoin blockchain, 3.79 million bitcoins are already gone for good based on a high estimate—and 2.78 million based on a low one. Those numbers imply 17% to 23% of existing bitcoins, which are today worth around $8,500 each, are lost.
While others have speculated about the number of lost bitcoins, the Chainalysis findings are significant because they rely on a detailed empirical analysis of the blockchain, where all bitcoin transactions are recorded.”
Hard to see how this is a sustainable situation . . .
