Buy in the red, sell in the green. If you're still holding, keep on holding. Consider increasing your position in the dip. Too many new investors who are overly emotional in the market right now, taking positions that are wayyy too big for them to comfortably handle a short term dip.

I don't touch my holding portfolio, pretty much only add to it - unless the price spikes real high (like when XRP pushed above $2-3), in which case I'll take some profits and rebalance my portfolio.

For me this has been perfect trading. Loving it. Buying dips and selling on the bounce, but only quick entries & exits - haven't taken any serious positions. Like in & out within an hour or two.
