Since now that you have a major update, can you please return all the bitcoin that we invested into upgrade? So we get a chance to choose other upgrade that we wish instead of the one getting nerfed badly.
I guess that wont happen, since the effect was bought and used and gold isnt going to be wiped. He wrote that the amount of updates you will have will be corresponding to updated prices.
Anyway everything for btc is going to be nerfed
