Can you buy Bitcoin for $1?

Can you really buy Bitcoin for just $1? It seems like such a small amount compared to the high prices we often hear about. Is it even possible to get your hands on a fraction of a Bitcoin with such a limited budget? I'm curious to know if there are any platforms or exchanges that allow for such low-cost purchases, and if so, what kind of fees or minimums might be involved. Additionally, are there any potential risks or drawbacks to buying such a small amount of Bitcoin? I'd appreciate any insights you can provide on this topic.
