There are ten, if not hundreds, failed pyramid schemes for every one on which you could make money. The schemes are not made for you. The way to earn money off of pyramid schemes is to create one.

Whether bitcoin is just a pyramid scheme or not, only time will tell. I don't believe so, but I'm not an economist, so who am I to say :).

I bought some cryptocurrencies on Coinbase about a year ago. Today I figured was as good a time as any to cash out. My net loss was about 70%.

I'm fortunate that this was a small amount relative to my net worth to count as a fun "experiment" and not a significant chunk of the money I need to survive.

Based on this N=1 experiment, I now feel justified in suggesting more profitable and environmentally friendly endeavors, such as lighting half your money on fire.
