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.
