They will tell you to buy and hold after they had bought it. They are using your FOMO. When many of you actually buy it, the price would increase because of the increased demand. But at a time when there is no longer buying order, the stagnation would start and they would sell out first and you would be stacked with high price. Never buy when the price is increasing. There are still lots of coins to trade. Remember many coins have no utility in outside world. The market is run by supply and demand. #WIF.
