I wondered why there were 2 different section on the wallet ("investment" and "account"), that were making harder to deal with the way to pay, and to understand in general. It looked like the old banking way where you have money you can spend and money that brings you more money.

I asked the CEO why such a thing, that was lowering the experience...
The answer was pretty clear: "Give us a week ;-)"

Thing they planned it from th beginning but had to deal with technical issues.
Cool they can fix it and improve the thing!
