Consider getting something other than Bitcoin, which is about the least stable of the many, many different cryptocurrencies available. Etherium is one of the best, which is why it is the base for NFTs. It holds its value a whole lot better, and you can easily convert it to BTC when you need to actually use it.
I bought $100 in Bitcoin on one day, right before the 2018 bubble burst. Overnight it dropped in value to $15.
Lol.
