If Bitcoin becoming a mainstream payment system in the future there will be no banks controlling our money ,and the ideal of faster more cheap international payment will be more interesting . imagine sending money to someone with out any fees ,well it will mainly reduce the government control over citizen ,but first bitcoin most become known to the world .so what are your taught on this topic
Even if bitcoin is massively adopted by Government, it will never take over our traditional transactions, Satoshi Nakamoto created bitcoin as an alternative method of payment that will throw out middlemen from examining our transactions and deciding when we will have access to our money in the financial institution and not totally mainstream the traditional transaction in any country that bitcoin is accepted as a means of payment. So the use of our currency and bitcoin will work hand in hand in paying for transactions in any country because there are some transactions that you can't possibly pay with bitcoin because of how small the money is, and then you can use some other currency to pay for the transaction. For instance, when you want to pay for a transaction of very small amounts, you will easily use some traditional method of transactions like in Nigeria,Ghana,Benin republic,cameron and Qatar to pay for that transaction because you know if you use bitcoin, it will cost you more because of the transaction fee.
In addition we can force any individual to use bitcoin but when changes arise from investors and holders they will accept the bitcoin massively.
