It is not too late in terms of investing because in the stock trading market there is nothing stable sometimes increase even may decrease sharply. You may be investing in bitcoin because the value of bitcoin that is currently down is also unstable, today bitcoin also dropped again when it is right for you to buy bitcoin or you also want long-term investment to gain greater profit. I'm sure in the bitcoin stock market will increase a lot before the year ends 2018 so if you buy bitcoin today and then sell it at the end of the year, you probably will really have a lot of money.
