hey everyone has panic sold something at some point (admit now.. well, except bob with his titanium training) but that was.. well that was some next level shit.
I still remember the "China bans bitcoin" crash of 2013 like it was yesterday. I was at the airport, watching the chart on my phone. It was all a nonstop sea of red straight down, and within an hour had falling well below my average buy in price. I felt sick, and certainly had many of these same thoughts.
But I hodled on. Refused to panic sell.
Yeah, it's happened to me too. In early January 2017 I had bought some coins around $1100 and then it dumped to under $800 (IIRC). I tried to sell on the way down, but Kraken saved me by not executing the order, due to their server s/w being run on ZX Spectrum 48Ks... Thank you Kraken, you saved me some losses from selling and rebuying.
So yeah, it's not so easy to keep your cool, especially in the early years of HoDLing. Would not do that now though. I feel I know how to handle it now, after years of HoDL hardening...
