These crypto-currencies serve a purpose, but there is no need for them to trade at $230 per coin. Would you feel better about the price if we use mBTC instead?

These crypto-currencies serve a purpose, but there is no need for them to trade at $230 per coin. Would you feel better about the price if we use mBTC instead? mBTC are only $0.23 right now. You should be looking at market capitalization, not price. As for crytpcurrencies being scarce, there are network effects that come with one system having the majority of the market share. Good luck convincing people HollowayCoin is worth accepting. Now, if some other decentralized payment system (that works with any currency and isn't a currency too) like Ripple gains adoption that could eliminate Bitcoin's network effect advantage. I believe this is one of the biggest threats to Bitcoin.
