Looking at the decentralized nature of crypto-currencies,Wonder if govt bans Bitcoins in future??Is it possible let's say by blocking all sites which relate to Bitcoin wallets/payments etc over the internet.In that case what would happen to our existing coins held in those wallets??
I do not think governments in countries that have too much influence on Crypto. Because this is an anonymous community and contains a lot of risks. They can not enter the market to sabotage or protect us. So you do not need to worry about it, this is a good market and it will last forever.
