I don't use them with dark.
Just with my real ID.
The 'internal' ecosystem that they built work are just fine. I.e. transfers inside wallet, using card, etc.
Personally I use them to make some cash from crypto (use their friendly exchange dsx.uk).
But as I know, if you want to go to 'real bank' world (like a SEPA or SWIFT that don't work now) they become strict like a any other bored bank. A lot of people reported about payments rejects etc.
I also tried to create corporate account for my onshore company for some SEPA payment, and just at verification process they started to talk like a bank. Want a lot of papers for some s**t, want to details about this, after it want to details about that, etc.
It's a absolutelly opposite to what they reported in the front of their site (when they compare itself with traditional banks
).
So, I think experience of epayments are very depend on how you want to use them.
