Proton is my favorite company when it comes to private file storage, email and VPN, and they do accept Bitcoin. You can get 200 GB with 84 EUR every 2 years: https://account.proton.me/u/0/drive/upgrade?ref=upsell_drive-button-user-dropdown.

If you want more than that, then I recommend pCloud. For 2 TB, either 100 EUR yearly payment, or 400 EUR for a lifetime*.
