Never ever deal to anonymous people and entrust them your money. People would still find ways to fool you that you must do this and that to get this wonderful offer. Keep your head straight and see that such offers with "too good to be true" schemes is an outright scam. Also, selling betting accounts is a huge no no. There are tons of betting platform that doesn't require KYC yet there are also KYC-required platform that only seeks for simple verification. If you cannot take the risk of giving your info to an online gambling platform, then choose those that you can play free anonymously. Keep safe dude.
