In my perspective, It is not too late to invest in Bitcoin.
A very low percentage of people own Bitcoin.
Take a look around you. How many people actually have Bitcoin?
Its a low percentage, perhaps around 4%.
Bitcoin is only owned by less than 5 million people worldwide and still has tremendous growth potential.
Everybody thought they were too late at $100, $500, $1000, $5000, and now almost $10,000.
Nobody knows the answer for sure but its worth researching and getting into with a small amount of money that you can afford to lose.
There's a saying in Crypto world.
Keep calm and buy bitcoin

No, It isnot too late to invest in bitcoin today. It is the right time. it's never late to invest in financial market and crypto or bitcoin also. when the price is low, you can invest it and sell when high.
