If you only have bitcoin right now than diversify your investment and invest in multiple other coins to distribute your risk of losing all with bitcoin. Bitcoin is going through correction which is actually fueled by bitcoin cash supporters. But sooner or later bitcoin will start to pump again, than all those fuders who claims that bitcoin will drop soon or it will fail completely will stop spreading such fuds.

If you really believe/afraid of price drop then sell your bitcoins(only few though) and or invest in altcoins( alts price might "drop" too with bitcoin price drop ).one should always have a diversified portfolio.

There will be some correction in the value of the bitcoins but there is no need to worry as the price will be recovered soon. If you wish to book more profit in the future then it is the best time to hold the coins as price will be increased rapidly in the coming months.
