From now on, I will no longer discuss the market, as it has misled many people. I usually buy coins about a week in advance, just focusing on one coin.
Then I calculate what price this coin will rebound at.
When that price is reached, I buy in.
I thought that after the coin I was interested in hit the bottom, the market would also be about to hit the bottom. The result was that the market continued to fall, while the coin I bought rebounded against the trend.
You say I'm inexperienced, I admit it, I really can't predict the market. I only know how to buy spot or one-time contracts.
Even if the cryptocurrency market goes to zero, I will not short it or use leverage.
