Gilding an investment applies a x7.77 boost for 45 Gold each. This boost is permanent, and the boosted investment turns gold. It is exclusive to Events and is more expensive than on Earth, Moon, or Mars, which boosting on those planets will give the same boost but only cost 1 Mega Ticket (20 Gold to buy it). Investments will stay gilded even if you reset to claim Angel Investors. To gild an investment, press the next to the icon of the investment you want to boost, then press yes. A sound will play and the investment will be boosted. Gilding has been removed in an update and now there are two Event multipliers. The first one applies a gold x7 boost to all investments for 20 Gold. The other one applies a platinum x28 boost to all investments for 45 Gold.
