The major government including Russia, China, and the USA (just to name a few) could also ban bitcoin and cryptocoins in general. My questions to you guys are: What do you think will happen to bitcoin? If any, what is your plan of action and what would you like to see from the community in terms of continuation and development? Bitcoin probably will never die but the banning of bitcoin could change the whole dynamics (let alone a temporary major price dip).
The three given countries you know are greedy countries as long as they are going to get profit with it and their citizens are getting good benefits from it. They won't ban it, but with your question. If bitcoin will be ban for those countries, I won't be affected as there are a lot of genius in the bitcoin industry that will keep on helping us to survive and earn with bitcoin.
