Ignore the value of the coins, not the coins themselves. Consider it a collectable, similar to the Pokemon cards you used to collect when you were a kid. When necessary, relocate them to a more suitable location and provide sufficient assurance that they will not be lost. That is all there is to it. Holding gets tough if you constantly watching the market as if you're going to get rich in a week or two. Don't do that, in my opinion. Holding is named that for a reason: it's for the long haul, and it's a very long haul at that.

Check the market once or twice a month, but always stay to the timeframe you've chosen.
