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

From people all over the world, very few know and have BItcoin. Only a small part. Yes, maybe this is because there are still many people who lay with technology and cannot know Bitcoin from anyone. Prohibitions in some countries also make some people are forced to stop having Bitcoin. But it's never too late to invest in Bitcoin and whenever we can do it.
