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! I can say that we are still not late to make investment with bitcoins. The value of the bitcoin is currently $8500 per each and it seems that it will continue to rise up. It is good if we have courage to make investment with bitcoins today.
