Nice site. What assurance or guarantee can you give that the verification documents and the card details will not be used for other purchases or purposes?

Well-designed site. Client identification is a good way to protect a business but it is important to protect the customer too.

Just a bit concerned about the bitcoin reserves being given as a solid and even 100,000 BTC which looks somewhat exaggerated. And also the credit card buy limit's ceiling amount of USD 20k. This is a bit unusual for a max purchase amount. It looks like it's designed to lure people to provide card and identity information using the attractiveness of the limits and reserves.

I might be wrong or just overly suspicious. Latvian banks might have such limits but I still find it unusual and exaggerated.
