I agree with you. The recession is still going and we haven't bottomed out from the bear market yet. Anyone who invests all of their funds now instead of just DCA really doesn't know anything, and fall for FOMO despite all of the signs.
We don't know if the $17k for bitcoin was already the bottom. But, it's true that we might see another low and it can be lower than $17k just to show the bottom.
It's okay if someone who invests all that he got understands what he does and is aware of the risk that he's taking. What's wrong and don't know what they do if they're just listening to the crowd and did it out of pressure and without analysis.
