Experience in trading cryptocurrencies, here are a few points for reference:
1. 60% Main Position: For long-term investment, the first year after the halving is suitable for accumulating Bitcoin, after which you can shift towards Ethereum. Currently, consider allocating low-leverage ETH + SOL; other investment logic poses greater risks over the long term.
2. Old coins, VC coins, and sector coins have low cost-performance ratio: it's better to shift towards the leading coins in various sectors.
3. Long-term low-leverage holdings in ETH + SOL: other coins may not outperform and have a lower winning rate.
4. Short-term speculation: if aiming for high returns with small investments, meme coins have stronger explosive power and overall odds, far surpassing old altcoins.
Although many people don't prefer heavy positions in SOL + ETH, most successful investors choose Bitcoin, Ethereum, and SOL as their main positions, which aligns with investment common sense and market laws.
