For a fraudulent app, I'm surprised at how well FTX as a platform worked.

I only played around with it for a while, buying/selling $250 worth of coins to try it out. I thought it was fairly well-designed, fast, etc. and on par with other tools like Schwab or Robinhood.

To hear that the entire thing was a fraud makes me think that they put a lot of engineering/design effort into making the FTX platform work. It was a fully-functioning product, not some Theranos-like facade!
