Option to switch between BTC and sats

Add your XPUB to generate a unique BTC address for every withdrawal. We won't save your XPUB but only create addresses and delete your XPUB after it.

Implement silent payments. This might be helpful for not having to generate a new unused address to withdraw to.

As a user, I want to transfer BTC to an address that starts with bc1p... directly so that I may use the BTC in my favourite wallet app (and take advantage of more TapRoot capabilities).

currently you are not able to see the total balance on a hardware wallet. You have to install a app like the BlueWallet with readonly access to xpub to see your balance.

Please make the user chose if the investment shows the payment minus the fees (like today) or the actual costs occurred for the user to purchase BTC. For a user the overall costs are much more interesting and all the other apps I tested are doing it the second way, which I find more transparent.

Could you change the +- development statistics if a specific time is selected by pointing into the graph? Today it is referencing to the beginning of the graph, however most apps are referencing to the current. This is much more intuitive as mostly someone what’s to know the relevance to now, not 24h, 1day, or one moth ago, as this is very random.
