$10k is broken and with this a lot of messages of people that sold at below $6000 trying to "cut their losses". Mostly because a lot of people was about to go bankrupt as their longs got liquidated. And with this, also came the super bears expecting $1000 a coin again, so they put really aggressive shorts, of course, only to get destroyed by the current recovery.
Lessons to learn for the noobs: Never panic sell, never margin trade, you can FOMO if you are here for the long term (5 to 10 years) since it doesn't matter if you bought at $20k or at $5k as BTC will be worth millions eventually.
I spend more than one year with bitcoin and I was well aware with this situation and never sold. I remember the time when one of my friend asked me that the price is going to go below $6000 and we have to sell but I told him that no matter how much the price go down it will reach back to its highest value and will go more and now he is happy.
I was about to get pissed of with the 6k price of bitcoin and was about to lose the confidence to believe that it will move up again.
But patience is really a key. Panic may come to anyone but if you have that strong fighting spirit and enough knowledge and expertise on the bitcoin cycle, then you will win.
I think that anyone who have invested would get either a little despaired or annoyed with how the price dipped really low especially after experiencing an ATH of almost $20K last December 2017. For someone who has invested a large amount of money, it would be inevitable to get a little scared. Seeing red and the charts go down would definitely dishearten most and make you lose faith. Fortunate are those who were able to stand firm and resist selling. Those who weren't able to are probably drying their tears right now.
