If bitcoin become legal across the globe that will be the start of the bitcoin mainstreaming and bitcoin will be used as a legal tender. But even with the legalities bitcoin needs to overcome some big issues such as slow confirmation rate, areas without electricity and internet connection, poor people who cannot even buy computer or smartphones. So possibly it bitcoin is legalize the usage of bitcoin will still be limited in urban areas with people who can afford to purchase computer and smartphones. The problem will hit the extreme poor people and the people in far flung areas that has no access to electricity and internet connection.
it makes sense, would be a major problem about internet needs in areas that are not affordable. but I think in the future, all regions will be affordable for the internet. and there will be lots of atm for bitcoin. so they can use or without a card.
I agree with you Bitcoin ATMs can solve the problem with the popularization of cryptocurrencies around the world. Perhaps in a few years we will no longer recognize the cryptocurrency market.
As the technology evolves, even urban areas will be reached by this technology in the future. Bitcoin ATM can help, but it will also require its users to stay using physical money.
also, if bitcoin will be recognized as a currency around the globe, I bet that this wont be the primary currency that we will all be using. Money from different countries have different value, it will never be equal to any other country.
