For me, security of the site is the most important thing. In the time I was playing NBA 2K21 before, I purchased NBA 2K MT from several sellers, and the amount was quite big. When the purchase amount is an amount that is certain the verification process is initiated. This can be an issue. I'm required to provide photographs that are related to privacy for verification. Following that I am extremely concerned that my personal information could be sold to these sellers.
Another important aspect is the security of the funds. There are a lot of fake websites that make use of the players' habit of paying attention to prices of goods and also sell low-cost products on their website, however they don't deliver the items until the buyer has paid. Many players who purchase game-related services from the site have had this experience I believe it's quite remarkable.
The most trusted vendor I would recommend is NBA2king and their service has always left me happy. It doesn't matter if it's in terms of speed of delivery or customer support, NBA2king has not disappointed me. Most important is that the site is extremely safe and offers the safest payment options because NBA2king is a partner with the payment methods. I'll Buy MT 2K22 at NBA2king!
