Thus, litecoin is a altcoin while Bitmessage not, although this is inspired by the Bitcoin technology. The Ripple system is not a altcoin, although there is a ripple altcoin call XRP inseparable from it. This article explains why there is a tendency to a single dominant currency for the network effect network effect Bitcoin the favors of overwhelming way on any of its competitors, and why should adopt a speech against altcoins instead to let more people be deceived by them.
Although a future imagine that most individuals will become so sparing as spender of bitcoins, you can conceptually separate the two uses. It is possible that people with a spare money even if there is no item to buy with the same N. It is impossible, however, spend a coin ie use it as a medium of exchange unless someone wants to keep it. If all those who acquire bitcoin did so with the sole purpose of spending it literally immediately, then it would be impossible for this to have any value.
Anyone who kept for any length of time would be willing to get rid of it at any price, even zero. Since the currency develops a little demand, so it can be used as a means of exchange paying those who want in exchange for a good or service. The total value of the currency market should be seen as roughly proportional, ceteris paribus, the liquidity of that currency.
This is the amount you can buy or sell the same currency without significantly altering its price. Although it is theoretically possible that a particular currency market value support any trade volume serving as medium of exchange, this requires that people are less and less willing to save it as the turnover grows.
In this situation, serious practical difficulties just emerging. If someone wants to buy something more expensive than the full market value of the currency, for example, you will be required to split the payment into multiple transactions.
Any imbalance between buyers and sellers more dramatically affect the market value of a currency if its total capitalization is smaller, that is, this would be less liquid.
