I would not jump to conclusions that the coin is useless. We would not accept it for payment if we were not going to build further value into it. 
Can you please give a link with the information about limited 24 hrs period about cache 0.01 accept rate? Why there was no info in the OP?
It looks like it was not there on purpose. I think a lot of investors\miners lost 50-100-150% of btc value because of their investments in cache due to that smart trick.
The price was stable for almost 1 month because of your promise to accept cache at 0.01 rate and after the cache price for asics was increased significantly, the market value dropped 2-3 times (please don't tell wierd stories about "bot" that crashed the price using maret manipulations). The whole story looks really shady to me right now.
