When I used to play with MEMEs, I came up with a 15-minute strategy: after buying, if the 15-minute K-line breaks, sell—at least sell a portion. TRUMP, the top-tier MEME, only has a holding period of three days. But after trading stocks, you have to shift your mindset: First, good assets are more important than good prices, especially when you're unsure about the right price. Second, hold long-term. In crypto, you need to move fast; in U.S. stocks, you need to hold longer.
