Yes you are correct, that's why people keep asking if it is too late to buy bitcoin, but I think it is never too late to buy them as of now yet because the market is still new and there is a lot of room for growth in terms of bitcoins price. It could go all the way up to $100k in the future, so if you want to buy bitcoin right now and invest it then go for long term then I don't think it matters to buy as of the moment.
