It's been a few years since Google, Apple, Facebook, and Amazon (often nicknamed GAFA) have shared the leaderboard as the most valuable companies in the world.
In the coming years, there is a possibility that GAFA's market capitalization will be outperformed by blockchain-based tokens. We witnessed Bitcoin's market capitalization reach $320 billion in December 2017, and it is not so far-fetched to imagine new growth bringing either this cryptocurrency or another promising one such as Ether to the $1.5 trillion threshold that GAFA struggle to reach.
