Value of cryptocurrencies: Why does noone make Bitcoin2, 3, 4,...? Cryptocurrency disciplee sometimes say that cryptocurrencies have just as much inherent value and potential as storage of value as fist currencies. One argument specific to the Bitcoin is that its value is guaramteed by the limited number of Bitcoins. However, I am very skeptical about this and similar arguments because of the following reasoning:

Why does noone use the exact same technology of the Bitcoin and create Bitcoin 2?  If they did, why would a Bitcoin2 be worth less than a Bitcoin? If it isn't, how can there be any worth in a Bitcoin, if there is the possibility that in five years there are a thousand different Bitcoin like system all guaranteeing the same anonymity, reliability, decentralized storage, and ease of use as the original Bitcoin? To me this is a significant difference to classical currencies which are linked to real governments and guaranteed by the fact that these governments work, pay and are paid with their respective currencies.

They have, there are hundreds of copies of bitcoin known as "altcoins", one prime example is bcash.

Because there is no demand for a bitcoin2. No one wants one because its not a real bitcoin. The only value bitcoin has is in the demand people have for it - how much someone is willing to pay for it.
