what do you think the amount of irrecoverable xmr is? with bitcoin it's estimated hat 4 million coins or more were lost by early bitcoiners who didn't save their keys or lost their password or their wallet.dat file or whatever.

when xmr came out i feel like people were a lot more used to crypto and had learened from careless bitcoiners and were a lot more careful with their keys and walletfiles, even though a large amount of early xmr is similarly irrecoverable. I think it probably much less than bitcoins estimated amount. What do you think? how much xmr is lost forever?
