Cryptocurrency is a decentralized encrypted 'cyber' currency where its economic value has yet to be realised, meaning not much corporations out there are willing to accept it as a currency in exchange for goods or services. Reason being as to why companies are not receptive to these currencies is also because of its uncontrollably, it is highly volatile, cyber security issues (hackers are targeting, and unknown to many its a heaven for Money Laundering). The infrastructure is building up, its security is being constantly challenged, but slowly and surely it will be integrated into alot of businesses due to its easy to use decentralized denomination. The next question is which denomination to buy into. As Jack Ma says, don't buy into something that you are not familiar. Take small positions to try out this investment, only you will know if its worthwhile after all.
