TLDR
Bitcoin is a poor currency because of high transaction costs and long confirmation times. Bitcoin is also not a particularly reliable store of value or unit of account. Bitcoin Cash and Bitcoin Core are the dominant models of cryptocurrency philosophy. But I favor a third definition, that I believe suits the nature of cryptocurrencies much better: they are communications networks first, on top of which value can be exchanged. Value in the Western Union franchise is not in the ability to transfer money between users, but rather in the worldwide network of franchisees running Western Union software.via the TL;DR App
