vincenzo credo sia il ceo (o comunque parte del team) di Conio. Quando si connette sicuramente potrà dare qualche info in più, fermo restando che ovviamente nessuno si sta augurando che Conio sparisca  

Conio approach to cryptocurrency use and custody consists in distributing responsibilities. It’s neither custodial nor non-custodial: no one on his/her own can transfer funds. As a result, no rogue employee in Conio can do harm; same goes for the third-party entity. Also, in case of emergency, a process is set in place so that the user can recover his/her funds.

One personal note. I understand this approach does not fully meet the original Bitcoin vision (summarized in the “not your keys, not your Bitcoin”). However, I personally believe this is quite a good intermediate step to get non-technical people involved in cryptocurrencies, and have them understand the importance of private keys.
