Yes, you should. Bitcoin is a great payment method but why would a webshop only accept bitcoin payments? Our experience teaches us that there is a high risk that this webshop is participating in some sort of illegal activity. Tread with caution.
When we notice illegal products, drugs or medicines are bought using our platform we will have to close your account. The same counts for purchases on the deep web.
If you are in any doubt please feel free to contact us. We might be able to provide you with advice.
