I think people have a particular fear before investing in bitcoin. I think the biggest worry of many investors before deciding to invest in bitcoin is unstable profit and the big threat from the hacker. So few investors agreed to take the risk to make a profit from bitcoin.
Many factors that scare to the investors of bitcoin, maybe they scared of putting money or investing money to said bitcoin but instead of gaining profit, the price cannot recover in the decreasing value, and also afraid in hacker.
