Mercuryo now supports the purchase of USDT without KYC:
No KYC purchases are now available for Mercuryo’s new users. Previously, to make your very first purchase in the wallet, you had to provide an ID and take a selfie with the document. The verification process takes 5 to 10 minutes, and it is only necessary to undergo it once. After checking the documents, the platform allows you to buy and sell crypto freely.
Currently, if you want to buy small amounts of cryptocurrency, you can do so without verifying your identity. Just register, fill in your card info, specify the amount, and as long as it’s less than €700, you’ll get your coins on balance.
Users can find more details via: No-KYC Purchases via Mercuryo.
