Only few or the elite can only unbind the cards, This forever goal of the team to make DEC at peg will never happen. Lets just focus on our goal to set SPS to 0.05 cents to activate the flywheel.
Why not just make burning mechanism for SPS to be converted to DEC-C. In the conversion, the minimum price of SPS is 0.05 (even if the real price is way below that). And the only purpose of DEC-C is to be used in unbinding cards. Will that be more reachable rather than insisting that DEC burn.
