Yes Bitcoin payment is fast and has a minimal service charge but usually no additional charge.
Aside from that bitcoin transactions does not need to give full information and so much papers to be filled up and no need to present valid ids.
i guess no. bitcoin is not fast rather it is super slow when doing any transactions whether its incoming or outgoing and it does not have a minimal service charge rather the transaction fees are friggin expensive as the bitcoins value keeps on increasing. though i think the only advantage of using bitcoin is because its anonymous and wont requires you too much information unlike any other payment methods.
