Combining the experiences and insights from the past 9 years of cryptocurrency trading, here are some conclusions for everyone's reference:

1. A 60% main position, making long-term investments in bear and bull cycles, the first year after the halving is suitable for holding mainly BTC, and later suitable for ETH. Currently, it is advisable to consider a configuration of less than 3 times leverage with ETH + SOL. Any other investment logic may not withstand the test of time. At present, only Ethereum and SOL are the most certain.

2. Long-term positions in old coins, VC coins, and sector coins have no cost-effectiveness. It is better to switch to leading coins in various sectors.

3. Currently, holding low-leverage long positions in ETH + SOL, any other assets may ultimately underperform, with a relatively low win rate.

4. If engaging in short-term speculation, with small bets for large returns, various old coins, VC coins, leading coins, and sector coins have no cost-effectiveness. It is better to see if there are any strengthening memes, whether it is on-chain with hundreds of millions to tens of millions, or all with billions to tens of billions, the explosive power and overall odds of popular leading memes are much better than the previous old altcoins.

Despite most people disliking heavily investing in SOL + ETH, most of the successful individuals in the crypto space primarily hold BTC + ETH + SOL. This aligns with common investment knowledge, as well as the current state of the industry and past patterns.
