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.
Yes right, this has happened to me, and most newbies when they first buy bitcoin and get a profit then they will buy large amounts even with all the money they have, they don't have the patience to wait at least a year so when they sell at a loss they write articles about the bad of bitcoin.
