In each transaction, the corporation is taking their percentage but also controls and monitors your transaction.
Let's say this, for example, being cashless transactions, for some people are treating it comfortably because as long as you have internet, you can send any payment to other people, with no need to bring all the time physical cash/fiat.
Same as Bitcoin, you can have your bank from just your mobile phone and pay someone in just 1 tap with no other 3rd parties needed.
