It’s less funny if I have to explain it, but why not. So, the underlying joke is that CZ is a scambag and shitcoiner. If he is embracing something or suggests something, this may imply that the suggested thing is compromised and no longer safe. To that end, the joke is that BTC is no longer what it was, therefore it is time to get rid of it and move on. Hope that made more sense 🫡
