Why cant you trade in coins for credits
Any game hype is good to spike the sales of equipment. "Earnings", coin room prizes and the Golden Putter fuel the hype here. Ball and CC pass sales profit.
Usually, the hype goes for some valuable prizes which may diminish the revenue. Imagine the "prizes" to be useless or worthless software items - how beneficial is that for the shareholders?
Rather than living on wishful thinking, I prefer a realistic view on the fun the game can give.
Enjoy the game, enjoy the views, and invest in a recreational pastime!
