In traditional banking systems, you are also using some bank's app "to change numbers associated with digital addresses". And they are also "claiming to move around something". And it works, until it doesn't, and suddenly, there is a need of "second bailout for banks". That's why Bitcoin was invented: we don't need "bailouts", because coins are simply worth more or less, depending on the outside world.

No, because people are paid, based on the number of posts they write. So, by writing an obvious reply, that "2+2=4", you can fill your quota easier on such topics.
