@Alpalaka Thank you for asking. Basically good. The 7th device will be put into operation next week. However, there are some issues that I hadn't expected - e.g. the effort involved, which is/can become enormous depending on the strategy. Nothing works here without a good plan if you don't just see it as a "hobby". If you want to earn money, you need a sensible strategy and have to grow up. Otherwise you'll be playing the money changer
