It's like I have to repeat myself a thousand times, but yet I knew this would happen (not everyone agrees on updates). We did this because the coins people had/have is crazy and completely ruining the game. We did this because we need to drop the coin economy and make it more stable. Taking it away from Sector is the best way possible to drop the coin economy. When it becomes more stable, we will slowly reintroduce coins back into the game, but for now you will have to mange with the new way.
The reality is that not everyone is going to like the updates we bring to the game and of course we know there is a risk, but everything we do is a risk.
Just think about it, coins will eventually come back, but hey look on the bright side coin value have increased.
