Interestingly enough, Polygon questions whether or not everyone receiving so much currency and bonuses could ultimately hurt and hamper the online marketplace. In games like Diablo III when the Real-Money Auction House was a thing, Blizzard had to actively curtail the drop rate of legendary items in order to prevent flooding of the market. Why would they do this? So that the price of legendaries could always sell for up to $250 real life dollars. They would receive a percentage of every sale, so it was wholly within their benefit to keep the market starved of legendaries. It was even revealed at one point that they had to balance the loot tables to ensure drop-rates stayed consistent so as not to flood the market and drive down the prices.
