Hi, Gents,
I think there has to be a way to create a tracking system for bitcoin. Every wallet must contain ids. Otherwise, bitcoin can be always used for money laundering. If you want to launder money, you can find a cash seller everywhere. After bitcoin is bought, noone can prove whose bitcoin it is. I think this is the only think that preventing bitcoin to become a global currency. Do you think it would worth this much if it is trackable. I dont think so. There will be altcoins that work with tracking system and ids. They will become a global currency. Bitcoin? I think never. What do you think?
It doesn't necessarily have to become a global currency per se, since as long as borders and countries exist, their respective governments will put up their own currencies, fortifying the ones that are existing if ever, nonetheless, with the current widespread state of bitcoin we can almost say that it is a global currency since anyone who has internet can get a hold of this and some other cryptocurrencies. In the case of having it become a global currency there are much more complicated matters that would need to be settled first before higher-ups consider setting up a global currency.
Bitcoin will only become a global currency if most of the governments will accept and legalize it. Regulation is still hot topic globally, there are countries that are favor and there are countries who banned the bitcoin. The decentralized characteristics of the bitcoin is one of the factors why there are government who doesn't want to legalize bitcoin. They are aware that they cannot control the bitcoin because there is no one who backed it.
