Listen to Danny Hamilton he knows what he is talking about. Bitcoin is not a company nor a service. It it much more a new kind of decentralized money.
And it is virtually impossible to hack bitcoin network. But there is nothing like 'trusted' satellite service which will guarantee that in case of their collapse you will receive your bitcoin back.
(I am not sure about Gemini, as they appeal to be completely regulated and probably offer your some kind of bitcoin version of Banking Indemnity Fund)
