Low volume currency , they can easily manipulate the price by giving fake trades and increase the price that way. Its not an honest trading views this just manipulated by owner or one of the supply holders so they can exit with high profit selling it to other traders.
No legitimate currency can give that profit in a day only shit coins do that.
yes it is true this is not honest, even if people have plunged into the coin they will not hesitate to dump the price of the coin so that it makes investors or traders lose. sometimes this must be careful
