I really want to believe that it works exactly as you write. However, there are many questions about bitcoin banking. For example, who is behind them? If behind them are the same as behind ordinary banks, then I see this as a risk. Yes, we own our BTC and the keys to it, but we will need to look at the conditions for connecting to such bitcoin banking, because perhaps they will simply offer to store our BTC with them and this will already be risky, because at any moment they will be able to say - oh, sorry everything was stolen from us, and we will lose everything. So, on the one hand, bitcoin banking is an interesting offer, on the other hand, there are a number of nuances that it would be desirable to know about in order not to lose your BTC.
