Not me, I actually witnessed the "TOP" of the BTC market, it was around 4AM EST and I was on my coinbase (lol) account. I hit the SELL button, and got a notice:
"This feature not available at this time" 😡😡😡 So I went to work, checked back later in the day, it had fallen off to 14k and I thought I had missed it entirely. But I caught the next peak, @ 17k and sold it all! Very fortunate. Just wished I had been hodling more at that time, my peak BTC levels were around 4 btc as I recall?

U need to follow me, "Task" ;-)
