Newbies lose in bitcoin because they are too greedy to buy bitcoins with all the money they have. Then they are also impatient and easily panic when the price of bitcoin drops. So they are afraid of losing more money. Until they decide to cut loss. In fact, when the price of bitcoin is corrected, we should buy it again.
it's true that a lot of greedy beginners want to make a lot of money in a short time and don't want to lose I have a friend he can't wait when the coin price drops and sells coins for fear of losing a lot of money even though I told him to be patient, the coin price will go up again just waiting for time but he doesn't care now buddy sorry because the price of the coin has gone up.
