Bitcoin wasn't created for a select few or for the wealthy alone. Digital assets like Bitcoin are meant for everyone, regardless of social status or wealth. Therefore, anyone can buy Bitcoin without exception, as long as they believe it's the best asset in the world. However, on local exchanges, you must have a minimum of $10 to purchase Bitcoin, as that is the minimum amount that can be used for a single transaction. However, I haven't checked whether $1 is available on global exchanges, as I rarely buy Bitcoin in such small amounts.
I think $10 is still relatively cheap, and almost anyone worldwide can buy Bitcoin with it. I agree with you because Bitcoin wasn't created just for the wealthy. It was created to eliminate the dominance of fiat money, which causes inflation every year, causing people's wealth to decline. But now, Bitcoin has become an investment asset, and only the wealthy have the money to invest large sums. We can buy Bitcoin for tens of dollars, but the wealthy can buy one or two Bitcoins, and Bitcoin's rising price makes the wealthy even richer. They can earn $1,000 to $10,000 just from Bitcoin's price movements. This is more profitable than other assets like gold and stocks.
