I didn't buy long enough ago to be rich from my investment, but I just choose a percentage of my portfolio that I'm comfortable holding in Bitcoin. If that's 10% and Bitcoin increases in value, then I sell until I'm down to 10% again. This means that over time I've sold a lot of my bitcoin and moved it to lower risk investments, but the dollar value of my bitcoin holdings has increased over time as well.
