TLDR: The $200 Billion number comes from the value of property and assets owned by the Libyan government and sovereign wealth fund. And while Gaddafi had zero qualms about using tax money to directly fund his lavish lifestyle, treating government property as his own and using the sovereign wealth fund as his personal trust fund, he never made any moves towards actually seizing the assets or principal of the wealth fund for himself, so technically it shouldn't count towards his wealth.
I am trying to find references for this lavish lifestyle claim. His Wikipedia entry says
"His home and office at Azizia was a bunker designed by West German engineers, while the rest of his family lived in a large two-story building. Within the compound were also two tennis courts, a soccer field, several gardens, camels, and a Bedouin tent in which he entertained guests. In the 1980s, his lifestyle was considered modest in comparison to those of many other Arab leaders."
I guess it's hard to say whether this amounts to a "lavish lifestyle" for a dictator.
First relevant looking link I found on Google:

If you had 3 million BTC, you couldn't sell them all without the value of BTC plummeting.
On the other hand, Libya earns about $20bn a year in oil exports. Subtract cost of production and then consider how much of that could have been taken by Gaddafi personally.
Interestingly enough, guess who else has $200 billion?

I'm sure they did a study to determine what wealth value was believable and anger inducing? Was $100 billion too low for people to care and $300 billion too high for anyone to take seriously? It'll be interesting to find ou thow they settled on $200 billion.
If I was maduro, I'd look for places to hide if the psy-ops start to mention his $200 billion or starts to focus on his wealth.
