This claim is absolutely ludicrous. The world economy as of this moment is worth roughly 90 trillion dollars. The market cap of this coin isn't going to exceed that of the world economy which is what it would take for this coin to achieve a billion dollar valuation.

Just to give you perspective, a million dollar valuation would be the equivalent of a 21 trillion dollar market cap or a little over 20% of the worlds economy. A billion dollar valuation would mean the market cap of the coin would be over 200x the size of the global economy. This is a pipe dream.
