It's said to be worth around $130 billion but that's peanuts in the grand scheme of things. Gold is one of the most liquid assets in the world and for that reason these 'discoveries' won't even dent the price. Bitcoin in that regard has a lot more maturing it needs to go through. If you have $100 million worth of Bitcoin to unload, you can easily tank the price down with 25% and depending on the exchange, even more than that.

EOS for example raised around $4 billion in Ether with their ICO, which is pure madness. They have enough coins to absolutely tank Ether down to the bottom if they want to push it back in the market. This is a proper example of how one event can and probably will significantly affect the price of an illiquid asset.
