Who cannot agree with this?! And the traders should know how to read the market, right? But how to do it? Step two keeping the money or keeping the crypto? In times when crypto is downtrend you should buy you say and risk money, bit what if downtrend continues? Selling in times when prices are rising and be in profit can take more time then you first thought. Keeping the money or crypto safe is normal thing to do, but earning and making profit from market fluctuations is moving you fund into money or into crypto, depending of the the market. Four step is like, second or fourth, trend is the friend if you can predict the market, and we already said that nobody can do it. Last year trend was pushing the price up to 20000 dollars, you sold at 5000 but in next few days price went to 10000? What you can do? Wait drop at 4000 dollars that will never come?
