we do not share your data with anyone and there are many ways to control the visibility and storage life of your data here.

be smart with your password, use tor or a vpn, and use pgp for sensitive communications.
I am using Coincorner and they are excepting cards. Very easy to use and you don’t need to get verified until you hit a spending limit (it’s over £500) however they are slightly more expensive than others. Hope this helps→
