Trading volume, market expectation, utility. Everything determines a market cap. But...let’s just take some company like Oracle for example. Like the 5th largest company in the world, has a market cap of 200 billion.

Bitcoin currently has a market cap of 200b as well. In order for a coin like ripple to be worth that, which we’ve already proven is difficult and rare, it’s coin value would only be a whopping $2, because it has a generous supply of 100,000,000,000
