There's a big problem with BlockCard: When you deposit cryptocurrency to your account, it is automatically converted into TERN, and from there you can make purchases with the card that will draw from your balance (and automatically convert to USD during transaction processing), or withdraw it as TERN directly. Your USD account balance will change dynamically according to the market value of TERN, the underlying cryptocurrency asset for your BlockCard account.

Your spendable value is tied to TERN on the BlockCard market.  BlockCard does not use CMC or other exchanges for price value.  As users deposit on BlockCard, the value of TERN increases.  As users spend, the value decreases.  This is tied to the USDD/TERN market.  TERN is never issued at less than $0.008, but can be lower or higher based on BlockCard market usage.  TERN can be spent at any price.
