Investing right now is the best choice, and this value is also more affordable and you can find benefits in the future, don't complain because all this must be time to become a bull.
investing in current price has same risk and profits.at this moment bitcoin price very cheap now , but dont forget it risky too if price suddenly continue bearish treand.and we should becarefull we our decision.
If we will keep on thinking about risk so we will lose this chance for me this is good time because price is not very high but surety and trust matters allot in case of holding, so keep on holding for long term dont panic so there is no risk but only profit, dont panic just invest right now I am sure you will be very happy later on for investing at right time without any hesitation for me 2019 will be great year.
