Hopefully anyone who is a member of this forum and is ONLY making minimum wage in a place like Bangladesh and/or any other country with similar kinds of low level wages, these people should be working towards increasing their wages rather than merely making minimum wage... and so maybe they should still be figuring out ways to make more and to be able to put that extra money into bitcoin.. . and surely make sure that their monthly expenses are covered so that they do not ever have to sell any of their bitcoin, except at a time that is of their own choosing, and surely many of us even realize that it could take many many years to reach a stack of bitcoin that feels sizable if you are ONLY able to invest $10 per week, which would be $520 per year, which would be $5,200 over 10 years, and so maybe 10-20 years of investing into bitcoin, even with a low amount will start to feel like it is providing a lot of options that had not been available without any kind of investment into bitcoin.
If we compare the average salary between countries, it is clear that an income of 15 USD/month is quite low. But if that amount of money is significant in some countries, it is not trivial for people there to invest in bitcoin for as little as $3 or $5 per month. Furthermore, if they can maintain the accumulation of bitcoin for several years and when the price of bitcoin skyrockets, it will also be a great asset in that country. I mean, maybe 520$ or 5k2$ compared to your country would be nothing but in Bangladesh or some low income countries it would be a fortune. With that amount of money they may be nothing in other countries, but in their homeland, they have certainly achieved certain successes.
Their assets and income also skyrocketed compared to the average income in their home country when they invested in bitcoin, meaning they were successful and changed their lives for the better.
Therefore, people with low incomes should compare with the average income in their country to accumulate bitcoins reasonably, do not compare with other countries, that will only make us more depressed.
