CZ said, dollar-cost averaging (DCA meaning). Based on the context, I think CZ is reminding everyone to turn on the DCA mode. Since he mentioned this use case, it suggests that we’re still in a bear market for now. Think about it—CZ, as someone who oversees the world’s largest cryptocurrency exchange, would see any market movements reflected in the exchange data. You’ve got to trust that he wouldn’t make baseless claims. As for which coins to DCA into, just go with the ones you like? I don’t think so. Don’t blindly listen to others. Most altcoins end up going to zero (those who’ve been through multiple bull and bear cycles will understand). You must stick to $BTC, $ETH, or projects with strong fundamentals and widespread consensus.
