A currency with no initial price tag, and which earns value over time? No exchange? What is it's value?
Perhaps I'm putting my miners hat on, but is the title of the post actually addressed by the rest of the post? As you know I'm fully supportive of all your endeavours here but until there is an actual value placed on BTM, then it is hard to evaluate the whether the other projects like getmarked will be viable. People, social media, websites, etc, will only adopt getmarked if it carries a tangible benefit. It's all well and good to build all these systems but at the end of the day, if giving or earning Marks has no intrinsic value, people won't bother.
The coin needs to dip it's toe in the exchange market sooner or later to establish a foothold. After all, if you can't buy or sell BTM then it really does have no value. My best suggestion is to continue to expand the nethash mining the coin. The IPM project is a good way of doing that. Exchanges keep a track of these sort of things but a low profile coin like BTM can get lost in the blizzard of "Look at ME" new releases. A smart exchange like Bittrex will pick up a promising coin (although sometimes they need a nudge).
Well, even though we haven't pushed to list BTM on any exchanges prematurely and no one other than tdokta has offered to sell his BTM(for a very legitimate reason I might add) there is still a minimum implied value which is represented by the cost of production. Which is probably somewhere around 0.00015 BTC at the moment. That is a very rough estimate and someone else can give you a better number but for the most part anyone offering to sell BTM would only want to sell at a markup to that price. If someone were to come on here and offer x amount of BTM for 0.0001 BTC I'd imagine people would be lining up to purchase it at the discounted price. In reality if the real ask price for people who need BTC now for other reasons is probably around 0.0002. The only reason someone wouldn't buy at that price is the fact that it's currently cheaper to produce your own via mining. But if there was some reason that a person preferred not to mine it's almost certainly a great price that will show a return.
edit: the network is expanding rapidly and the difficulty is rising with it as I can see so my numbers are old and wrong. But the general point still stands. Someone else who's currently in the mining game can probably give you some accurate numbers.
