Last note on crypto:

Anything based on current encryption and work factor techniques has a shelf life. Bitcoin will not be forever. It's shelf life is under 10 years, very possibly under 5. If you want to beat the final market crash, make sure to keep on top of quantum computer news. In under a decade, there will by systems that can easily crack into any wallet and steal the contents. You want to watch the news and the second they become truly accessible to places like China, Russia, or North Korea, or in any way, commercially, you want to GTFO. It may even become available in under five years. Note that China especially already has robust quantum computing, it's just such a finite resource right now and of low enough qbits that it's utility wouldn't be wasted on something like bitcoin (even for a yuge wallet). That will be changing...
