Also they said if Monero surpasses the volume of Bitcoin in the next two month, they change their bio to "Europe's biggest Bitcoin and Monero Store" (which should obviously name Monero first but whatever xD).
Btw the numbers for coincards.com show a similar but not as devastating picture:
Email is encrypted in transit using TLS. Use a provider like Proton or Tutanota that also end-to-end encrypts your inbox, and you should be fine. But I agree, it's not ideal.
SMTP doesn't allow requiring TLS encryption between email servers
That means TLS encryption can be defeated by MITM modifying the handshake to say one side simply doesn't support TLS. Boom, no more encryption.
Email is not confidential unless you use e2ee, such as PGP.
Using Proton or Tutanota with coin cards offers no protection here because the problem is coincards. One option is for coincards to let a user enter their PGP key, like facebook supports. Another option is for coincards to hire a security engineer to tell them to stop fucking emailing private keys, and just display them on their website like any other decent gift card vendor.
