if I think it's better not to stop and continue to buy lots of coins that have great potential because the price of the coin is cheap and to be held only until the coin has a large increase or if it is sold can get a good profit later
well, you have to realize that these coins have no value. They are not backed by any country, asset or fondamental. They are basically worth 0. Their only value is speculative. Holding coins hoping they will bounce in the future may yield results but it is one of the riskiest strategy, especially given that money has been flowing out of the market for now one year. If no new money pumps back into the market it will inexorably go south. Brokers will try to jack up bitcoin by all means but if bitcoin fails to gain more public acceptance, its value will gradually goes down to zero
