This week and next week, I will review other people's logic of altcoin trading, the logic of entering or exiting the market. Because it is too boring to only do Bitcoin, and also because I often read the experience of those big speculators in the stock market recently, I think it is actually quite interesting to play altcoin well. I will use a small amount of funds to practice in the next two weeks. The yield just broke 600 today, but it was all made in Bitcoin, so I just tried altcoin today.
