I think the whole idea of cryptocurrency is to use it as a currency. Meaning that it has to be used for the exchange of goods and services.
Today all cryptocurrencies , including Bitcoin, are used as commodities. People use it as a mean to increase their "fiat wealth".
Investors just buy and sell in the hope that they will make fiat money.
Miners mine it and sell it to make money.
Even merchants that accept cryptocurrencies, simply set the prices according to the fiat exchange rate. They probably immediately sell the crypto in order to get fiat currency.

The real revolution is when people stop caring about fiat currency and start using crypto currency without thinking about the fiat to crypto exchange rate.

For example:
Normally an IT specialist can provide his services to companies for 1000euro per day.
If he was to provide his services for 1000 zeitcoins per day without thinking about the exchange rate, this would inevitably creating an upward pressure to the exchange rate of zeitcoins. If a lot of people did that, then inevitably the zeitcoin would reach euro parity...

I do realise that this is difficult to do at the moment because people need money to survive.
But it would be possible for people to provide services for a smaller price than they would in fiat. This would still help the coin gradually gain value. It needs years but it is possible.

I think a good start would be the people in the cryptoworld. We all have skills. Maybe we can offer some of our time for a smaller price in Crypto.It doesn't have to be only the developers that help the coin. We can all do it.
