I have not done extensive research on the BCC card but I know prepaid Visa and MasterCards, backed with Fiat before they are issued are quite common. To me it looks like Bitconnect is doing that. You would convert from BCC to cash and then load the cash on a PrePaid card. This would make very little risk for Visa or Mastercard, and those type of prepaid credit cards are available from most major retailers for a few minor fees. That said, I do suspect BitConnect someway is using this to hold onto peoples money longer. Mastercard and Visa avoid bitcoin because it could be a long term competitor, but a few other legitimate companies have ways for you to easily spend your crypto. (with Visa/MC cards)
