Maybe the way we can protect our cryptocurrency is by buying the coin at a low price and sell at a high price. That will be done if we have skills in trading so we can know when the time to buy and sell. Without having skills, it is hard to get the right price because sometimes after the price down, it will go down for more but then the price will increase later. So we need to learn about how to analyze the trend and maybe we can place a two or three order to anticipate the lower price.
