When I listed these the credit value was somewhere near 4000 per $1. Now it's 7200 per $1. Everyday that credit value increases, my items value decreases. Listia is getting out if control.
The credits increase according to what the market will bear. As long as people are willing to pay more credit points, the value of the credits will continue to decrease. When/if people refused to pay such high credit amounts then the credit values would increase.
When Listia started allowing the selling of credits by Listians and turned Rewards to auctions there was a massive surge. I tried very hard to keep up with my values so I would not lose money on my items but it did not take long before I was unable to list my small less valuable items. So many have left this venue or have refused to spend. I have set limits on what I will pay for items as well. Good luck in future. We will see how it ends.
