It's not going anywhere, It's not gonna plummet to 0 in a single day. it's here to stay since more and more companies are coming forward and doing ICOs instead of getting fundings from VCs. So one day maybe it will be stable and be even more valuable than diamonds.
That One day may take many years before coming to happen right?
Bitcoin is extensively getting higher and higher each day but Beating Gold is like being adopted the whole world and that would be more waiting just to happen.
Everything goes to this, because the cryptocurrency very quickly reached incredible heights and this is just the beginning, and when the whole world will recognize cryptocurrencies, then the prices of cryptocurrencies will begin to grow even faster and many cryptocurrencies will be more valuable and more expensive than gold.
Thats the main objective of Satoshi Nakamoto for Bitcoin to be used by every people all around the world but it comes to be hard and after 10 years of existence still not even half of the world is accepting this.
