How is this service useful if I lose 2 key? It is an unnecessary service only looking to get paid from subscription fees which is giving a false hope of security.
I don't understand what you mean. If you have a 2-of-3 multisig vault and you lose 2 of the 3 keys then obviously your money is gone.
I am not saying this sevice is good or bad, although I posted that there is something I dislike that they do.
