"Lost coins only make everyone else's worth slightly more. Think of it as a donation"
I have never lost any coins I've owned but reading some of the stories of private keys being lost, old hard drives been thrown out with hundreads of bitcoin on them I can only imagine a few people on here may have lost some.
Have you lost Bitcoins?
How much and how did it happen?
What happens to lost Bitcoin?
Well.......
If you have lost Bitcoin I bet now no matter how worthless some of the coins your holding, it will never happen to you again!
