For what is really I like the most about in bitcoin was the flexibility of sending money in different places, even internationally it can be use as sending money according to the country they belong. Very fast and transaction charges was very low 
Yeah and with existence of bitcoin now we don't have to depend on banks and WU for sending or receiving money and also we don't have to pay them higher fees as we can now easily do with bitcoins with just click of a mouse and that also with the least fees.
