The problem that is tackled:
"Imagine that Alice decided to sell her old mobile phone to Bob.If she sells it for bitcoin or another crypto-currency, then she is at risk.Let us assume that she wants to sell it for 500 USD in bitcoins this is 0.313194 BTC at the rate of 1 596,45 on May 8, 2014. After selling the phone the next day, she wants to convert coins into dollars, but she finds out that bitcoin is already worth 1 300. As a result, after converting the received BTC, she has lost 92,84 USD, and in the future she will unlikely use such a method. And millions of other people and online shops think the same way: to use crypto-currency as a mean of payment is risky.That is why it is difficult or to be more precise it is impossible for bitcoin and other crypto-currencies to become a widespread mean of payment. As a result, the main holders of crypto-currencies are speculators and long-term investors. "
