Bitcoin is very obtainable. You don't have to buy one unit of Bitcoin, it can be broken down and you'll get $1000 worth or $100 or $10, whichever amount is closer to your reach.
You're also not late, Bitcoin is in its second decade and is still only used by a small minority of the world population. You're early.

Do your reading across the forum, if you're looking to buy search up best exchanges and processes, best wallet to store in and how to secure that wallet.
