Beware tho the shards/ crystals / clusters market r a fantastic place for bot pricing to breed.
So if ur gonna sell ur going to have to make ur listings stand out if you want to get ur stuff sold.
You can sell lower quantities for a slightly higher price for ppl who just want 50 shards instead of 200 lol. Or u can sell an almost similar quantity but at a lower price. Cuz the listings will never be empty due to 24/7 shard farming bots XD.
