If bitcoin is proved to be useful and successful in other countries. The government which ban the bitcoin will legalize it and its people will benefit from it.
Yeah right if more people will use bitcoin and it will legal in every each country the price of bitcoin too will increase more.
For now we are just few and i think we are just 5% using bitcoin.. because they are still afraid to use bitcoin because of many scam allert..
but i think the main reason of less investors of bitcoin is the awareness, they need awareness about bitcoin and hope that will start taking interest in bitcoin, still there are more than 80 % people who even do not know about bitcoin then why wil they take interest in bitcoin.
