Just remember that holding also requires patience and control. It also requires sufficient resources that you don't have to sell during times of lower prices.

If you're barely getting by and see your holdings worth a fraction of what they were worth, it can be really hard not to sell, especially if you strongly feel the price will keep going down.

Those are the times you should be buying more, albeit incrementally keeping enough spare fiat on hand to buy if it dips further.

Accumulating fiat from your normal income during periods of flat or rising prices is a good policy. That way you're always prepared to buy the dip.

Just never sell.
