Is there any research available on lost coins, especially DOGE? 
By lost I mean lost forever, for example because of lost wallets, forgotten passwords, transactions to wrong addresses etc. I am interested to see how much coins disappear from circulation and what is the estimated range for the market capitalization if those lost coins are excluded. It is also interesting to compare lost coin value in one year to the amount of coins mined during the same period of time.
San to say but it was not recoverable,because all wallets are secured by our own private key that even the developer has no access about this.i have once lost my private key and I accepted that theres no chance of regaining my coins By lost I mean lost forever, for example because of lost wallets, forgotten passwords, transactions to wrong addresses etc. I am interested to see how much coins disappear from circulation and what is the estimated range for the market capitalization if those lost coins are excluded.
