Taking into account my experience the best strategy is:

1) buy when the market cap is falling;

2) buy at the lowest price taking into account the last month through convert limit orders;

3) when you earn 10%, 20% put it aside and convert it into a stable coin like usdc and leave it there waiting for the market to drop again to convert it again;

4) invest in memecoins only 10% of the portfolio;

5) always keep the BnB because you always get something through the various launchpools, megadrops and airdrops.
