I know buyers selling for a major loss and walking away because of the increase in rewards. It makes each coin less valuable the more supply that comes onto the market. In the case of Digibyte they have a decrease in rewards by 1% compounded every month, the buyers know acquiring coins gets harder. I bring this up because they are used an example to say the supply is much higher then Gulden, this is due to more exchanges and trader access and rewards decreasing each month.
