Yes it is very sad for us and all the crypto community is very sad and frustrating. However, this time the buyer buys Bitcoin and buys it. I hope that soon its price will come back.
Its nothing surprising because at the past of bitcoin, it always drops it value, and it will increase again. Bitcoin is unstable currency, because bitcoin is volatile, it means that its value is rapidly changing and its unpredictable if its going to increase or decrease. For me buying now is good because the price is lower, later it will rise up again. Bitcoin is used to these situation, so dont panic and just wait for its time to increase again, because it will, maybe before the year ends.
