I agree with you and I want to add that bitcoin is a long-term investment, so being a long-term investment, we are talking about that at least the person should hold it for 4 years so that there are no losses, because historically the price of bitcoin for more If it drops a lot in certain years, it still manages to recover in 4 years. So a poor person would need to have the following conditions:
1 - He would need to have money to invest in bitcoin, and when we talk about money to invest in bitcoin, this poor person would need to have a decent amount of money, something like $500 at least, it turns out that poverty in first world countries is very different from being poor in third world countries, where $500 is a large amount. The minimum wage in my country, for example, is $250. so a poor person would have to work hard to get $500 if they don't have a job
If a person doesn't have the money but have the skills and the knowledge, he can acquire Bitcoin by looking for a job that pays in Bitcoin. He can do freelancing that pays in Bitcoin as a side job aside from his full time job. This way he can accumulate Bitcoin with his time and effort and not with his money.
True that, at the current situation, Bitcoin price increment is not as high as it was in its early years. To have a significant profit that can change life, one needs a huge amount of investment. A hundred or a thousand dollar investment won't make anyone rich nor have a life-changing effect. If one wants a significant profit from his Bitcoin investment, he needs more than two cycle which can take more than 8 years of waiting which most poor households can't afford.
