Those who say multiple purchases don't count, please be quiet. If you don't know, don't talk randomly. When buying Alpha, you should try to buy in batches; large purchases can easily lead to being trapped, and try not to choose BNB for the chain unless you are very optimistic about a certain coin.
The summary is as follows:
1. Multiple purchases, take profit in batches;
2. Try not to chase after meme coins;
3. You can choose coins with large pools to buy;
4. Gas consumption: Base=Sol<Bsc<ETH mainnet;
5. Look at K-lines more, try not to buy at high points;
