lost or held by long-term holders. This means that currently 33.96% of the total supply flow of 21 million units of this digital currency can be considered out of circulation.
Lost or held by long-term holders ... so long-term holder is never gonna to sell? As far as i know they simply choose all wallets with did not move coins for 5 years. I think this estimation is super far from real number of lost coins. If I lose my priv key today ... my lost bitcoins will be counted into this number after 5 years...
5 years ago circulating supply of BTC was equal to 15.8 mln. If 7 mln was lost 5 years ago (and are counted currently as lost because of not being moved for 5 years) means that close to 50% of present supply is unavailable. Or ... what in fact make this while 33.96% estimation useless ... "in hands of future long term hodlers" which may start to dump anytime.
