"One of the main problems cited about cryptocurrency is the fact that it's volatile; although many users and merchants may want the security and convenience of dealing with cryptographic assets, they may not wish to face the prospect of losing 23% of the value of their funds in a single day." – Vitalik Buterin. Founder, Ethereum.
