No you are not late. You are perfectly right in the right place. As the market is growing and the predictors have predicted that the year of 2019 will be a good year for cryptocurrency, bitcoin will grow in the days to come. So still bitcoin is at a lower price. So do not wait for other better opportunity or time than this one to buy and hold bitcoin.
I am also sure that Bitcoin will already cost more than $ 8,000. But still put orders on the 7500 and 7000 dollars. I plan to buy Bitcoin to 12000 dollars.
