What about someone who buys 2 of a knife, because they have the disposable income. They hold them and the value goes up by a bunch when they sell one after a year or so to cover the price of the keeper. Is that flipping? Or a good investment?
I'm torn, usually I'm not a fan of flippers, because they beat me to the buy I wanted. Fast sellers seem more like poorly capitalized members then bad actors to me. Unless I can't get a cool knife and they taunt us with their success by selling immediately, not realizing the value (as a tool) of what they bought for a second.
Does it really come down to how quickly one sells the buy for a profit? Is it the percentage of total posts in exchange for sale section?
I've resigned to picking up users when I can, eliminates the whole flipped or not flipped discussion as I don't regard members who use and later sell a flipper per se. Just a member who's eye moved to another knife to use as intended.
