Where did you read the post? If what is meant is to help improve someone's economy, it might happen. Bitcoin has value, poor people will not get anything from Bitcoin if they do not have it. More precisely, Bitcoin can be used as one way for people to profit from investment. Of course, it's not that simple.

In another case, if you are someone who saves money in a bank. Bitcoin can be an alternative to one of the good stores of value to avoid inflation that occurs in the fiat that you save in the Bank. I will not say poor people, but people who care about their finances must think about how to store their assets so that they do not experience a decrease in value. Bitcoin is a good alternative for this.
