If someone buys, then you have a decent price. If no one buys, then I'd say your price is too high. Can we agree on that?
In my opinion, there are plenty of people with a lot of LTBc, who don't really have any immediate use for it. Just because Melotic isn't doing a lot of LTBc trading doesn't mean there are not plenty of LTB content producers who would give an interested buyer a better deal than you're offering. Note that the amount of LTBc you're offering is just a bit more than a writer can get with one article.
Again, if you sell, then you'll prove me wrong. My bet is you won't find a buyer at this price.
