Bitcoin is here to make transactions made online easier and faster. It introduced a peer to peer system which eliminates the third party system in terms of sending funds to anyone at any part of the world and it is done within minutes.
Not to mention that it eliminates the sheer inconvenience of having to use native currencies when travelling abroad. If Ethereum is your gig, you can use it from anywhere in the world (apart from any countries that aren't allowing crypto of course
)
