Have you tried proton drive? They offer a lot of different services and accept bitcoin payments.
I haven't used that, but I'm pretty happy with proton pass and email.
For the record, don't put your BTC in the cloud. It's a disaster waiting to happen

The same ones that offer proton email? They hate Tor users, cannot even register an email through Tor.
Also when they accept BTC, can you send them mixed coins or they will complain too?
