Perhaps some poor people, considering its already quite high price, have assumed that Bitcoin is only for the wealthy. In fact, anyone who wants to buy Bitcoin is always welcome, regardless of their status. This is the unique thing about Bitcoin: it can be obtained by anyone without having a lot of money up front. However, if you want to buy a lot at once, you obviously need a lot of money. However, if poor people are patient enough to use their time and buy in installments from their monthly income, that's not a problem, because such installment purchases can also build up a large amount of Bitcoin, even if it takes a little time to acquire larger amounts.
It seems to me that the more expensive Bitcoin becomes, the harder it is for people to buy it, because in their perception the price is very high. Of course, you can buy it in parts, but not everyone is ready to buy when the price has already exceeded 100k, and I also doubt that Bitcoin right now is the asset that can bring big profits. It is a long-term investment, and among retail investors, not many are ready to invest on a long-term basis, everyone wants quick profits.
