Its already dropping again right now.
Just relax mate. Yes that dropping moment always happened even before beacuse of its volatile attitude which is exchanging time on time its rate in the market. So dont panic and relax .you should buy a more coin now instead of getting panic of this situation if you have a money that not needed in a moment then you must buy now to multiply that money when bitcoin reach again 5k or more. Yes as we see bitcoin falling again but there's a time that bitcoin will fight and it will climbed again and make us profitable which is buy low and sell high . .when bitcoin drop we buy and when bitcoin rise we sell .that is the purpose of falling attitude of bitcoin . "chance to buy a low price". Instead of getting higher and higher we have no chance to buy because we cannot afford its price. it is good that bitcoin fall sometimes beacause of reason that we can buy bitcoin in a cheap price.
Yes do not panic and do not think to immediately sell it, if bitcoin value continues to decline. Should save while waiting for bitcoin value back up, if you have a lot of money, better buy and store it when bitcoin value down or below the cheap price. So that later you can get bigger profit from the sale when bitcoin value back up and higher.
