Yes this would be late to buy a lot of bitcoins and expect a lot of income.But you can still join the party. Bitcoin today is very expensive almost $15,000 so if you ever buy today you will still gain profits but not as big as those who are holding their bitcoins for years and years like 5 years or more. They must be a millionaire today because bitcoins before are just worth nothing like cents when they first came in and who would expect that they would be as expensive as it today and still they can increase a little more. It is up to you it is not bad to try. If you are planning to invest $15,000 worth of Bitcoin imagine how many you should've bought 6 months ago but you should still invest and avoid regretting it again.
