Since Intercoin’s communities can peg their currency to any outside currency, it logically follows that Intercoin can spin up a “virtual version” of any coin, including coins currently built by countries like Estonia, Venezuela, and so on. They can build it on any technology they wish (ERC20 doesn’t handle enough transactions per second to be viable for payments at the moment). And then, their individual citizens may decide to exchange it for a “virtual estcoin” or “virtual petro” by buying into the Intercoin economy!
Because Intercoin is held on full reserve, every currency is fully exchangeable for any other at any time, limited only by publicly posted restrictions of the respective communities. If Intercoin’s network allows faster payments, and better liquidity between any currency pairs, many people may decide to buy digital representations of their USD, BTC or any other fiat or crypto currency.
Thus, no matter what technology was used to launch the original currency, the holders of that currency may buy into the Intercoin ecosystem for the benefits, and also enjoy all the community applications on top because Intercoin has programmable community money.
In that case, the result would be capital flowing into the Intercoin community, and staying there because trading virtual representations of Bitcoins and USD, and doing everything else with them, is possible without having to pay market spreads or intermediaries.
In short, Intercoin can become a sort of universal, decentralized exchange that is not controlled by anyone, able to generate virtual versions of any virtual currency.
