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

You right mate, and i absolutely agree with your perspective about bitcoin itself, when you investing money into bitcoin even slowly but surely. because every Investments are very tricky and its hard to tell if were too late to invest into something or not, its just not possible to predict if its going to go up or down in the future. for me bitcoin is best invest especially for long term, and we are never to late for that.
