Yes it can! As bitcoin remains on top and develops well, it will become the mainstream and it will be of great help to many by then. Looking forward that it will indeed happen for the good of many.
For the next decade I believe bitcoin will be an important currency, especially as a digital currency. As an illustration, now bitcoin is already known and used as a means of payment by millions of people around the world. There are some countries that refuse to use bitcoin, but citizens can use bitcoin with foreign proxies, because the internet cannot be stopped. Bitcoin with fiat currency for the next decade will work together.
