Before investing to bitcoin this what I stand to my own decision. I trusted to the tech, to bitcoin and blockchain network that is behind bitcoin. And mostly I trust bitcoin that it will comeback and that skyrocketing scenario will be seen few more days or weeks from now on.
2018 is still long, we are still in the beginning of it. There's a long way for bitcoin to recover from the highest price we've seen so without a doubt that it will recover and comeback to that price.
