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.
I have read a few whitepapers and research upcoming ICOs and there is one who really caught my attention. Most of Bitcoin and cryptocurrencies have nothing behind them but Propthereum.io are an asset back cryptocurrency with potentially great coin appreciation. Definitely one you should check out for!
