I understand buy low and sell high, but I don't really understand how this works. If everyone wants to buy low, then how are you supposed to sell high?
I have a key and am looking to profit from it, whether it be gaining a ref or two. Can someone point me in a SPECIFIC direction as to what to do first?
Every time I make a post selling something, it either
A) Never gets bought
B) People buy someone else's item because they have time to bump way more often than me
