Bitcoin security

Some companies are beginning to take preventive measures. CoinBase is a custodial service, which contains the private keys of a client-of the kind that, if lost, would make the bitcoins permanently inaccessible-and as such, can provide a certain level of security in case of the death of a person. The company requests documents such as a death certificate and testament to transfer the assets.

It is not a solution that some enthusiasts want to use, since the idea that another person has custody of the bitcoins is contrary to the nature of decentralization and user control that aroused the interest in the anonymous currency in the first place.
