The cowardly countries have tried to ban BTC but it just makes them look stupid because it cant be stopped. At the most they are just delaying the inevitable.
yeah as you can see it in russia , they ban bitcoin but the more bitcoin user popping up
as long as there is an internet access bitcoin will last forever
so if a country/group want to shutting down bitcoin they have to shutting down internet too
which it's almost impossible to do.
Exacly how come that countries can ban or monitor who still uses it knowing btc is an online money needs an internet connection before it use ,to be able to stop it they must down their system or they will coordinate to the developers of btc or to the internet couriers. There are more problems each countries facing why focus on banning btc.
