I'm tired of investing in what I can "afford to lose"... I want to invest an amount that would be LIFE CHANGING if that investment pays off.
What does it mean by "afford to lose" I don't have debt or bills that I'm worried about. I can lose $10K and be okay, but I certainly dont wipe my ass with $10K so I can't say I can "afford to lose it" like it's chump change.
You should invest in a way that there is as small a chance as possible of all your assets becoming worth zero at the same time. For instance a portfolio of 20% real property, 20% banknotes, 20% gold, 20% mutual/retirement funds and 20% crypto, fulfils this criterion. If real property loses its value, gold goes up to more than make up for the loss. If banknotes lose their value, crypto soars. Etc.
I don't like the "can afford to lose" rule because people misinterpret it to mean "insignificant amount". In fact it means an amount that hurts, yet does not cause house resizing, change in lifestyle or turning to crime to make up for the losses. It can be 10% of net worth, but for some young and relatively poor, even 100%+ is in fact amount that they "can afford to lose", literally.
To have a chance of life changing payoff, you need to invest very methodically, which basically means investing a large enough sum in a quick succession, and then waiting with the investment that it pays off, and never sell. An alternative is to set a selling schedule based on new higher prices, but this method requires more initial capital. I still suggest it because the occasional selling keeps your hand in the game.
