I guess the reason why I other countries do not allow bitcoin and even ban it because they will have less income in tax, because bitcoin do not have tax, like having million transactions, government cannot get anything from that million transactions made, they cannot control the finance of the entire country which each country must and need to have a control unto because there might be an abuse of using the money if not controlled. We really need to enlighten the government with the advantages of having this bitcoin to our country despite of the less income tax that they will receive.
