I have 10 lost ,I lost them in 2011.the price in that year is less than $1😄
That’s a lot of bitcoins, so sorry for your loss. I hope that’s not all you had, it will be comforting if you had some bitcoins stored in a wallet. Re
And you?Is there a place to collect the lost bitcoins (I mean the private keys is lost,and the bitcoin in that special address stay there forever)

There is no way to recover lost bitcoins, I have read articles online about softwares that generate thousands of private keys that may or may not contain some lost bitcoins, there has been no record of success and I don’t think anyone should waste his time on such treasure hunt.
