I witnessed the entire process online, but I made very little money, only a little on bnsol. The main problem was that I didn't have a habit of putting money in the contract, so when things went wrong, I couldn't transfer it. When many coins plummeted by over 90% in the spot market, I couldn't buy them at the bottom. Later, when I finally could trade spot, I bought the bottom on bnsol and made a little money. What a shame, what a shame! Witnessing a historic moment, it was more severe than any flash crash I've ever seen.
