At some point in my dad's #bitcoin journey, I'll teach him that you take profits when you buy bitcoin and not when you sell it.
But it's too soon now.

Here’s something I have found useful: rounding down to the nearest thousand.
If your stash is “worth” $950 dollars, in your aggressive accounting mark it down to $0.
Later on, the stash is worth $1950, in your aggressive accounting mark it down it $1000.
This helps psychologically deal with the volatility.
In the fullness of time, this tool won’t be as useful if the person comes to viewing Bitcoin from its own unit of account rather than a fiat one.
