Having earned a hefty profit from the sale of Armor, Rocky naturally wouldn't let this huge sum rust in the vault; he immediately spent all the Gold Coins.
Making money is hard, spending it is easy—everyone understands this principle, and it's even more applicable to Rocky, who now governs two Sky Cities and one land-based hub, meaning there are not only numerous places to spend money, it practically disappears into an endless pit.
Take Thunderhawk City, for example, which was undergoing a city upgrade. Although Rocky had already allocated tens of millions of Gold Coins for this major project months ago, this was now ancient history, and those millions had already been almost entirely spent within a few months.
