The idea behind the card is reasonably solid, but the execution is seriously flawed.  The repeated data point referenced here by the BlockCard team is that “BlockCard does not control the TERN price” and it's volatile and it is described in the "how it works" page, is valid.  BUT - They explicitly don't tell consumers that they have a secondary price at load time that is an off-market price, so the act of loading can cost 20-40% of the deposit value.  THAT is not documented and shared/disclosed.  Since they are providing the deposit service to convert other Crytpo assets to TERN - they should disclose anticipated costs of that service (especially when it is a massive portion of the deposit).  What they are NOT disclosing is that there is VERY LIMITED liquidity on their internal process/market for doing this.  Which if you watch the pricing on “their market”, shows 20-40% movement at each major deposit.  In addition, their internal pricing:Published USD/TERN price:(HTTP Removed for post)Internal processing prices when converting [as provided directly from BlockCard] (even from a stable coin) (HTTP Removed for post)As you can see, their internal fills (when you deposit something not TERN [like BTC] and they convert it to TERN for you) is not based on the open market (but a closed market stellar price) and shows significant variance shifts from the open market – see the jagged shape.  Any large deposit appears to be disrupting the market (thus the VERY jagged price profile in the chart).  Which is why large deposits are missing 20-40% of the face value when finally credited.  It does appear that you can game the system by off market TERN deposits – but there is so little liquidity in the asset and minimal market making, so that is not as easy as it might seem.  The technology of the platform and user experience is nice.  If BlockCard moved to a stable coin like USDC / Tether or a low transaction cost common coin like Litecoin or Bitcoin Cash, the card could be VERY usable.  As it sits, it is ONLY usable for small transaction /load amounts.  Though the load system is “legal”, it is HIGHLY misleading.  Given the lack of open market visibility on the “fills” (converting other crypto to TERN), there is very little transparency on if the anticipated value to be loaded on the card before the user tries instantiating the “load”.  There is really very little liquidity, and it is unclear if the company is taking an extra VIG on the transaction as is common in the Foreign Exchange market, so the obvious thought is they are taking excess value (someone is making that money).  The company does not publish the prices (exchange rates) of all load transactions and the distribution of all capital flows at each card load.  If they did, it would go a LONG way to clarifying if it is just an early market and they lack liquidity (and the solution will get better with time) OR if they and their vendors are taking HUGE fees.  My opinion is that the solution could be a good one in the future, but the lack of market liquidity means consumers loosing significant value if they try to use the card for anything other than tiny load values.  The Market Makers supporting the loads are making a ton of money and in the process the customer is getting taken advantage of on large card loads.
