Well yeah you're completely right, but many people just want to hold and see if their had a high profit. I mean they buy at a very low rate price and then will sell if price is at their highest bid on their list. But i think it will be nice if many people doing like what you said.
They seem to have no choice since the market condition aren't good so holding is the only way to avoid more lose and wait till it recover. Its soon to recover anyways.
