I know it is a tricky question. What do you think, how many Bitcoins are lost forever and are 'out of the network' by lost private keys?
difficult question , there is not person calculate .
but i think very many because users bitcoin many too
I agree we cannot calculate this at all but I think there is lost a pretty large amount.
Nope the fact is that there are lost a lot of coins but that we do not have stats of this at all!
of course there are many people who have lost their bitcoin. and we could not make the statistics about lost bitcoin. I myself several times lost bitcoin, luckily I had never get to experience that my bitcoin stolen
Same here dude, I never experienced that my coins are stolen, I always double check my wallet everyday, the links that I clicked, and programs I installed if there are some hidden malware behind. And yes that's really true almost everyday many users lost their bitcoin around the world, but there are no lists or stats of lost bitcoin, but its really helpful if developers will do things about this, about the lost coins
e.g if there are dead wallet address (I don't know the term but something that almost years that this address is no longer be used but it has balance example, minimum of 0.01) that have amount on it they will be monitored or be listed in blockchain.
