I have a question. Suppose Bitcoins price is now $20000 and i have 1 Bitcoin. And i want to sell my bitcoin but accidentally i put the selling price at $2000 and confirmed it for sale. Then what will happens next? I know how buying and selling works on exchanger. In order to sell something someone have to buy it. But what happens if there are no buy order at $2000.
Forgive me if i say something wrong. I didn't try it on exchanger because of the fear of losing money.
As long as you place a sell order at a price lower than the current level in the market, it will be filled immediately and you will not have a chance to revert later. This is a fundamental mistake in trading so always trade in a sober mind without getting drunk or panicking, just one small mistake will make you regret not in time.
Because you sell only one bitcoin but if you sell in large amount of bitcoins and below market price it is called market dumping. Once the market panics, many will accept to sell bitcoin at or below the market price to cut losses. This is how the market falls.
