In 2009 the TARP program was the US Government buying shares of high-finance companies that were about to go bankrupt --- using taxpayer dollars. So now the American taxpayers own Lehman Brothers, Bear Stearns, and AIG? No, it didn't really work out that way, did it.

Also, the number of people who were paying a $300,000 mortgage for a house that was only worth $180,000 was incredibly high.

Hope somebody can come up with a list of ways that a dramatic crypto crash will cause harm to US taxpayers --- again.
