The beauty of bitcoin is that the demand does not stay the same, rather it is increasing, there is even a speculation of exponential growth of Bitcoin demand making bitcoin price to swell up to half a million dollar. 
As cryptocurrency, Bitcoin has proven advantages. Bitcoin is not a currency that is kept in Banks. Its decentralization means no one can control or regulate Bitcoin's price. International transactions are done relatively quickly and that Bitcoin is one of the cheaper ways to spend international payments.
Bitcoin indeed has a huge potential. Not only as an investment but it has provided opportunities to many people to earn and gave them economic benefit. it empowers people to efficiently exchange goods/services in a peer to peer fashion without depending on a currency, monetary system or banks to do so.
