Blockchain research startup Chainalysis in its study of bitcoin-wallets has concluded that access to bitcoins worth $20 billion is lost forever. According to the company, the main reason is the loss of private keys for access to purses.
Chainalysis senior economist Kim Groer claims that the company will not help users recover lost bitcoins. However, the Federal Bureau of Investigation of the USA (FBI) during some investigative actions was able to restore access to cryptocurrencies in the amount of $1 billion.
Wallet Recovery Services said that their specialists manage to restore wallets access in 30% of cases. According to them, everything depends on the correctness of users’ personal information, on the basis of which the keys for the entry could be created.
