Crypto ABC - Why are cryptocurrencies so popular?

Cryptocurrencies appeal to their supporters for a variety of reasons. Here are some of the most popular:

• Supporters see cryptocurrencies such as Bitcoin as the currency of the future and are racing to buy them now, presumably before they become more valuable

• Some supporters like the fact that cryptocurrency removes central banks from managing the money supply, since over time these banks tend to reduce the value of money via inflation

• Other supporters like the technology behind cryptocurrencies, the blockchain, because its a decentralized processing and recording system and can be more secure than traditional payment systems

• Some speculators like cryptocurrencies because they're going up in value and have no interest in the currencies' long-term acceptance as a way to move money
