Mind you, these digital currencies aren't much like a safety-deposit box (i.e. the actual Super Safe Cash Box.) They're more like a bank.
Safety-deposit boxes are dumb stores for objects. They've never been marketed on features; in fact the opposite, they're marketed partially on the idea that nobody can open them but you. Therefore, no services (e.g. automatic transfers) can be built that depend on someone being able to automatically do things to your safety deposit box without you there to watch.
Banks (specifically, checking and savings accounts) are not dumb stores of money. They don't even hold onto your money; they leverage it into investments. Banks have always been built on "loads of advanced features" like compound interest, wire transfers, cheques, etc.—things the bank can do to your money because it is not, in fact, a Super Safe Cash Box. It's a convenient, maybe-safe money-management agent.
Bank accounts are only really trustworthy because of 1. a long track-record, and 2. being insured against losses (in banks' case, by the government.) Those are the same requirements I would put on any digital-currency+contracts system before I considered it trustworthy. Digital-currency+contracts is trying to do banking with banking features, so hold it to the expectations of a bank.
