Correct my math, but it seems like that's approx 1/3 of a percentage point of BTC's market cap at $1.56 trillion.
And the money didn't disappear; it still exists.
So: why did BTC (overall) drop by 15,000% of the actual loss (which actually isn't a loss at all to BTC as a whole)
Seems like markets are really driven more by emotion and perception than fundamentals, but I'm neither a psychologist nor a trader.
