We need to achieve a huge adoption before we can be considered as a strong currency and when that happens the government cannot do any bad thing with a huge volume of supporters because we will beat them for sure.
As of jan 2016 there are 100m users of bitcoin and is already a strong crypto currency.
i don't see any reason why gov. would do anything about bitcoin, and what do you mean
we will beat them even with (lets say) 70% of population is using bitcoin fiat money will still
win. bitcoin is better of being an alternate currency than being the main one.
100m users? From where did you get this estimate?
Isn't it tough to get an estimate because people have multiple wallets and addresses?
