Doesn't make any sense TBH. We should've seen it starting to replace conventional currencies by now.
i am not sure for now, bitcoin need more to replace conventional currencies, people should use bitcoin in every where and need to be approve by the government. but if its just for the internet currency, i think bitcoin will be stronger than other because of the easy and simple to use bitcoin and we should help bitcoin to be known by many people.
Yeah as it's found to be the internet currency, bitcoin needs more time to go mainstream. Being a mainstream currency is not that simple. It takes years and years to get a stability in the growth as well to go mainstream. When you consider gold or USD the history it has made is very big history to hold the place.
