It is not late now to invest in bitcoin eventhough the price has significantly gone up. But do not feel bad buying at this time because there is more rise in price to catch up with in months to come. Bitcoin is an investment that can not make you loose everything you have invested especially if you are going long term. Give yourself one year or two and then you go and sell. Anything within two years from now will mean you are in good profit and the right thing will be to sell off before another drop.
