Imagine to yourself how many wallet with astronomic sums of bitcoin people lost or lost because they didnt give a fuck when bitcoin was tiny.
and those wallets..will never get acceesable
Somebody's lost is somebody's gain. Well its their fault really because they didn't care about their bitcoin. And we can read countless stories like that online. They can just bang their heads off and nothing will bring them back what they have lost. And it turn, its our gain, because what other's have mentioned, it add to the scarcity of bitcoin which will result in a higher price in the market. So its a gain for us.
I agree with you that, somebody's lost somebody's gain, and we are the gainer, who uses bitcoin now.
I guess we need to thank them because there will be no chance that the bitcoin going to be in a very low price like cents per bitcoin, so it is impossible now that the bitcoin will crash into nothing value.
And yes Op, those lost wallets or old wallets are not accessible and impossible to get again by others
