There have been lot of wallet have gone since bitcoin creation , a cousin even lost His bitcoin
back in 2015 (maybe he is not really interested in this so he miss managed the wallet address) but never that
happened in me though I believe that there are many bitcoin that is hanging around the air now for being a
lost bitcoin.
cannot be detailed , because who knows that we have lost our wallet till we announced it?
You have a point there , and yes how can we be so sure when it is indeed might be lost and
who will knew until the owner admitted it was gone completely.
