What are you even talking about? Bitcoin is just a tool people can take advantage of to transact with or to hold wealth with. Bitcoin can help people be more financially responsible and save more money, but at the same time bitcoin could be used to buy addictive drugs that could potentially destroy a person's life. How 'good' or 'bad' it would affect a person's life totally depends on the person using it.
well, what more can i say here. i dont know what the OP wanted to read here. but it is just the same as fiat, whether you will use it for good or bad intentions, it depends on you.
what bitcoin is offering is like, if you want to transfer money from one country to another, you can use it to transfer incurring competitive fees as compared to traditional remittances like WU.
i know for a fact that there are some people who are using bitcoin to transfer their remittances because the transactions are fast and easy with relatively low fees. so if that is one example of making a person's life better, then yes it is. bitcoin is doing its part. whether you are dealing with bitcoin or fiat, it is all the same. if you want to do good or bad in your life, is a matter of personal choice.
