If you exhibit this character of extreme fear when price of Bitcoin drops, it is a sign that you have invested much more than you are supposed to invest in Bitcoin and that is not a healthy practice. It could also mean that you are not well aware of that price of Bitcoin goes up and sometimes down and never in one direction. Whichever be the case, I think you need to make serious adjustment in your investment approach if you must have peace of mind while being invested in Bitcoin.

It is character like yours that have motivated people to start working on different methods of investments that will take away things like this fears. If you spare some time to learn about the DCA method, you will realize the focus is to eliminate the kind of fear that you expressed by allowing you invest just little amount of your money per time and done consistently. When the amount invested is not a huge burden to your financial obligations, you will not fidget when price is going down and you will also be able to continue buying since you are already convinced that the investment will require some time before you begin to expect some profits.

I seriously recommend the DCA method for you.
