Ask HN: Cryptocurrencies
However I am struggling to understand the economics of these cryptocurrencies and I am hoping the HN crowd can shed some light on it by answering a few questions.
The original Bitcoin paper was titled “Bitcoin: A Peer-to-Peer Electronic Cash System” however from talking to people who have Bitcoin they don’t want to use it as cash because the price is too volatile instead they are basically buying Bitcoin as an investment. Is this a narrow view and are people around the world using it as a cash system? If people are not using it as cash is this even a problem but then what is driving its value?
To me it looks as if the Bitcoin system is wasting vast amounts of computing power and in turn electricity. Is this actually scalable or are we going to reach a point where it no longer becomes profitable to actually mine Bitcoins and as a result the network dies.
Etherium is another cryptocurrency that seem interesting due to it’s smart contract system. However is anyone doing anything useful for the end user with these smart contracts? I had a look at https://dapps.ethercasts.com/ and I struggle to see the value of it from looking at the list.
I apologize for coming over quite negative but I feel as if I am missing something and it is difficult to find balanced arguments when looking at cryptocurrencies. It seems to either be the “next big thing” or simply a bubble.
