Recently, I've been particularly fond of the term 'Asset Classification' that I coined.

It means not to put all your eggs in one basket when buying things.

I especially enjoy switching between multiple platforms to check my holdings.

Buy a bit here, buy a bit there.

The advantage of this is that if I lose here, I might find I'm making money on another app, which reduces my previous unhappiness and keeps me from getting too worked up. If I lose here as well, I just switch to something else. So far, I haven't encountered a situation where all four platforms resulted in losses, which is why I've found that I no longer operate emotionally. It's quite perfect!
