Your second part is exactly what I did with my first bit of Bitcoin. I got it at about $50 and sold when it first hit the $1,000+ range - I was able to catch it at about $950 as it came down. I have that paperwork I wrote for that Bitcoin framed in my office as my most valuable to date work. lol A reminder of sorts.

Now my wife and me put money in Bitcoin as a "last chance" rainy day fund. This has only bit us once in several years where Bitcoin had dropped from about $2,300 to $,1900 at a time we needed it. Those are some great odds in my opinion.

Now we simply forget we have it until we need it. My shift card stays hidden out of sight and only comes out when we need it.
