I think bitcoin is the new era of currency because you can use it in different kind of transaction like shooping in online market and many more. I think bitcoin will be the best world currency in the future and it will consider as a real money that you may use even in offline market but I guess some of them already accept the bitcoin as a payment.
Its not a mere guess; some online websites are already accepting payments in bitcoins. Bitcoins are definitely going to be legal worldwide soon due to their increasing usage and popularity. The world has already been turned into a global village and bitcoin is the best currency to be used internationally in the future.
