Environment and society improve when the members of this society have high moral and financial standards. Important to notice money isn't everything, though.

So we can say bitcoin can be helpful as investment on long term to protect patrimony against inflation and as a potential mean of payment for online jobs that weren't disponible to common people like us before the invention of bitcoin.

As we earn more money, in great part thanks to bitcoin, we have conditions to spend more money in our local societies, warming the local markets, and going for environmental-friendly products and services, since their costs are more expensive, so we need an improved income to have access to them.
