Furthermore, if you decide to set the price for your services in your currency high enough (so as to at least cover your expenses) given the settled market exchange rate for your coin, you will be losing anyway. Why? Because the profitability of mining is essentially limited by the cost of electricity, while your costs (not even speaking about profits) will obviously be higher than the cost of electricity (since they most likely will include it plus a lot of additional expenses)...
So whatever price tag you set for your services, you will be heavily losing as compared to just selling them directly for fiat
As i understand you right... It's the question about market liquidity. The more services will use the currency the more we can sell on exchange without significant price change. There is no profit now yep, just fun
.Nope... In fact, I assumed that there is already enough liquidity in the market ("given the settled market exchange rate for your coin"). This is a shaky assumption (in reality things would be worse for you), but it was necessary to show why you will most certainly lose profits or just suffer losses even in the case when the exchange rate was fixed. Liquidity won't prevent you from subsidizing your users (if they pay for your services in your coin)...
Unless you cap the amount of coins allowed to be mined, indeed. Otherwise users will steal from you arbitraging the system
1. You are right if there would be just we, users and our services (like twitter, dropbox, hosting, etc). But as i said that end-user services aren't primary target, it was just part of the explanation why now it's more interesting for service owners.
2. That services won't be twitter, dropbox, etc things requires data-center.
3. In general there will be still some point where i can get profit anyway (like mining litecoin for example) so the whole assumption is not very solid imho.
It's useful already without any additions for "look previous post" guys. Like spam protection systems etc.
