Using BTC gives you the financial freedom to transact globally,BTC provides economic stability and Newfound freedoms to the world making it true game-chaging technology.
This is one of the objectives satoshi nakamoto has in mind to with his team to create bitcoin,
• Use as fastest process to make transactions intercontinental
• It reduced more stress of delay when transacting to another country, mostly from one country to another. As I said above
• Bitcoin is freedom currency that you will transact all alone with your partner without a third party
• so our objectives is for it to be embraced globally as means of transactions and payments of goods and services.
Depends on what you are using of course, there are "cheaper" methods globally as well, but depends on where and to where you are sending, using what. Let's remember that bitcoin isn't free to transfer, we are paying a good sum to send it, which is called the tx fee, and that is not cheap these days.
There are even nations that have financial deals with each other where you can send for free, without any charge at all, and instantly. The reason why I am in bitcoin is not the pace, or the fee, it is the fact that it is decentralized. There is no FED here, there are no central banks, we just control it and we make it do whatever we want, because we own it. That is not something that exists anywhere outside of bitcoin world.
