that is something that i hardly understand too. why would you sell less of what you paid?
unless there something wrong with the coin of course
Plenty of reasons... Maybe you really need the BTC to pay some bills. Maybe you want to try and induce panic selling in weak hands so that you can buy up more at cheaper prices. Maybe you are one of the fools who are easily manipulated into selling for cheap. There are a lot of reasons why people do the things they do in the market.
