1. The characteristics of the last market segment are: Bitcoin may move in a zigzag manner, but altcoins are likely to perform strongly, because if they don't, they won't have a chance. It's a chaotic situation (everyone gets trapped), and there's a rotation in the market (this is just a prediction, don't take it as a guarantee); 2. A brother just asked about Ethereum $ETH, and I maintain the view that Ethereum will outperform Bitcoin. This round will be led by Ethereum, but I personally won't focus on Ethereum for the last wave; I can't help it, I'm not good at trading this last surge that keeps going up without pulling back; 3. Diversifying positions, spreading out investments, and batch trading altcoins might be my strategy; diversifying means that the position in each coin won't be very large, so the psychological pressure will be much smaller; 4. The expectations for the last wave won't be as high as the third wave, so it's better to have lower expectations and adopt a mindset of being satisfied with any profit.
