It's not too late to buy Bitcoin yet. Statistics say that since the introduction of bitcoin in January 2009, it has been profitable to buy bitcoin more than 90 percent of the time. However, it should be borne in mind that it will not constantly rise in price. Moderate risk when investing in bitcoin persists and is inevitable.
Its never too late to buy bitcoin now, although it would have been better earlier, at this level we have not even reached half of where the bull run is going, so you still have something good to profit with if you buy, I will even advice many not to sell yet out of excitement. Wait a little more there are still a lot to hit before the year ends.
