PS: Edit: I have a few over 1000 on an giro account, so no interests and the 2% price inflation. I want to buy lenses for my camera or even a new camera. But I wait. Why do I wait, when every euro on my account is decreasing in value? Because it isn't. If I wait, prices of lenses or bodies will go down, or newer better devices will appear. So for that particular need, my euros are definetly increasing in value over time.
So people will have better life being a euro maker, not a lens maker
A few people sitting there making money without doing any real work, and let the others slaughter each other(competition) to chase for those money, is there any good reason for that?
