So basically a two of three mobile multisig?
Discussion
Actually the one im currently on is just a 1/2, but using my mobile key as my account key for access. So the mobile key is a barrier if anyone gets my phone, but its not attached to the bitcoin.
Im still experimenting with trade offs, but just really loving the Tapsigner as the prinary signing device with day to day use. Probably a 2/3 is the best all around for security and ease of use.
