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

I think it is not too late to own bitcoin. You just have to work hard right now to be part of it. You can try small and save in alt coins or small trades. You just need the perfect timing before taking the risks in this market. If you start in the lowest point, you will grow more. So have patience here, this is not a race. I agreed that we should keep calm because in the end, we will all be successful.
