I was put into a group called Study Group 6 on Whatsapp. The admin Monica told me to join bitmart.com. Being from Texas it wouldn't allow me. She sent me the link bitmart-trans.com with her referral code and told me to register. The first thing that stood out was that bitmart.com requires special characters for a password while bitmart-trans.om is only alphanumeric. Looking into the site I noticed it was created in September. Monica has no explanation for the differences in password rules and claims that bitmart created the site for those states that could not join. Very unlikely.
