Thank you for your feedback.
It is definitely our goal to increase the interest rate, but if we do, it will be the same for everyone. We launched the investment platform just a few days ago, and everything needs to settle in first.
At the current 2.5%, the interest rate isn’t incredibly high, but it ensures that we can definitely cover it with our current profits. If the expansion of our business with the new capital goes well and our current profit margin of 19% scales accordingly, then we will definitely adjust the interest rate. For everyone equally.
The idea with the toasters is cool, but doesn’t everyone already have a toaster at home? 
Thanks again for your feedback, and best regards!
