Without anyone telling me this, I already knew that there are fake Gold but Bitcoin is not fake actually, it is just that the price of Bitcoin is not stable but we can invest on it for long term and make profits more than investing on it for short terms.
Gold has existed from many years but look at were it is now, I do not think that it have any more potentials like bitcoin, and Bitcoin is only 16 year now but there is more potentials that it is going to go further in the next 10 years. The reason why Bitcoin is superior to gold is because it is decentralize.
