Just remember...when selling you get hit with tax consequences (in the US).
So selling a big chunk is not the best strategy (unless you're just in it for the fiat and supporting your benevolent government with more money).
Personally I was able to retire and I can pull out $35k of my bitcoin every year tax free. I don't have to work the rest of my life.
To me that seemed a bit more important than anything I could cash out and buy.
