The rise of MEME relies on a few points: it had previously dropped too badly, there were very few buyers, and even fewer holders; once retail investors have cleared their positions and sold what needed to be sold, a wave of upward movement can occur, attracting a large number of short sellers to enter the market, which could potentially trigger an unexpectedly massive surge.
So what should you do when encountering such a coin? It's simple, just make short-term gains. Then don't touch it, don't look at it, don't short it, let it go wild, or drop to zero, it doesn't matter. But never easily short MEME. Remember how MEME rose last year.
