I wanted to throw this topic as a question but I feel confident to say that the days where anyone (poor) can easily acquire one Bitcoin is over. The reason why I feel such confidence is because, at the beginning, things was easy, and people where living good life because things was very cheap then, jobs where available, 1 month salary can serve a house hold budget and yet there will br enough money to save for that month but looking at how things have changed right now, salaries of so many people can not even complete their house hold budget for a months, it's only rich people that are able provide all house hold needs, settle all bills and still have more money to save and also buy 1 or more Bitcoin.
Do not use your financial situation to make judgement on what others can do or can not do. People have money if you do not have, there are some people that are waiting for Bitcoin to get to a bigger value before they can start investing because by then they will believe that Bitcoin can not crash anymore because of the amount of money that would had been invested into Bitcoin by that price. There are some billionaires that can buy as many amounts of 1 Bitcoin as they can buy. There are companies that are buying more than 1,000 Bitcoin through DCA every time that they invest and there are individuals that can be able to afford investing that amount in Bitcoin. Beside you do not need one Bitcoin to have invested in Bitcoin but any amount you own is fine.
