Most people in the old cryptocurrency circle believe that as Bitcoin and Ethereum ETFs are accepted by Wall Street capital, the volatility of Bitcoin decreases, the price increase is limited, and the time for growth is extended. Consequently, they feel that (in a unit of time, say 2 years) the opportunities in the cryptocurrency space have significantly diminished. This statement cannot be said to be completely incorrect, but I believe that viewing the opportunities in the post-cryptocurrency space from a different perspective will show that they are still as abundant and rapid as before: one-third of the funds should be allocated to Bitcoin, while the remaining main positions should be chosen from 2-3 suitable POW coins or strong coins between numbers 3-100, treating them as Bitcoin from 24 years ago, which can still achieve the cyclical returns of Bitcoin from before. This kind of strategy is likely to gradually become popular in the cryptocurrency space. The three key points of this strategy are: 1. One-third of the position in Bitcoin must not be lost 2. Coins beyond 100 should not be selected (the number of coins in the future should reach tens of millions, and 99% of the coins will gradually lose attention and eventually go to zero) 3. It is best to choose POW coins or strong coins.
