The majority of gold in the world is paper gold, what you buy in stock markets as gold is not real gold. Cryptocurrency is decentralized and because of that many people favour it without it being part of an corrupt system. As of now bitcoin is still king but we cannot say for sure who rules in the future. There is ripple which is favoured by bankers, but so what? ripple is only one of the technologies out of hundreds and even thousands. Some day we might look back and laugh at the currency prices of what is now. Just upvoted by way.
