Crazy that privacy tops the list for 2026

Went over my final DMs with Do Kwon from April 2022. It’s crazy in retrospect, knowing what ensued just a few weeks after. My last DM to him is offering support in May 2022, after Terra collapsed — which remains unanswered until today.

The irony is that in April he felt at the top of the world. This was Do at his worst — he became increasingly dismissive (in a somewhat respectful way) and unavailable.

At the time, I didn’t know the extent of the fraud. I had no idea he faked numbers with Chai, preminted $1B in UST to ‘solve’ the cold start problem, had Jump bail out UST a year before, or that he likely was extracting hundreds of millions in dollars in the days before and AFTER the Terra collapse.

This is also why, for the only time in my 11 years in crypto, I endured significant (thought luckily not devastating) losses.

Multiple lessons in there IMO. The first is — don’t be a dick to others, and stay humble.
