Observation and experience. As more and more people are coming to the crypto market they need to have something. And this "something" must have reasonable perspective of growth. Also this "something" should better not be totally mined. Dime is not connected with miners, it is at the moment it's weakest feature but in some time it will turn to be its advantage. Looking on the sales of cryptocurrencies on ebay want to tell you that at least 35 millions of DIME were sold in last 3 days at the price of about 6USD fiat for 1 million (that's true, have all the auctions saved))). So for now the expected price for DIME is far more 36LTC satoshi.
But now - it is up to INF to grow. Market have its logic, Infinits must grow to a least 600 before DIME will shoot. Hope that INF holders are reasonable guys and will release their holding to the market step be step.
Also there must be some time for market to dissolve the first time proposal of DIME. According to my observations it will be about 500-700 LTC. Depending on the DIME investors experience (will they be able to release their holdings gradually) and overall cryptomarket newcomers it can take some time. But if the situation will remain - it will happen very quick. People on ebay yesterday was giving already about 120GBP fiat for 50 000 doges and I have no idea when it will stop. Everybody in crypto world must say thank you to DOGE
And finally - as for now it is a developer's team and community who makes the value of the coin (look for example o Tips after community takeover). So - sound policy, some innovations, moderate but frequent giveaways (no more 1kk DIME for nothing), imo it will work fine.
P.S. Will add another 2 cents. For today (only my opinion, count yourself please) relational price for ifc is about 620-670 (no, I do not have a single coin in this crypto), after it hit 600 and (if) stabilize about this price, so after a week after DIME will reach about 60 ltc satoshi. Once again, I do not even "advice" to do anything, it is your own money, so you decide. Also I do not know the current alignment for ifc. But what I know for sure is that any development in this life is going step by step only and things are heavily connected together. For DIME investors I would suggest at the moment not to surpass the line of 1/10 inf price (now it is about 470) and if it will happen not to burn the market hot, it is up to the big DIME holders now to give good suggestion in about 45-47 on the market, let people make reasonable "come in" into coin and make investments for future several months at a good rate. Come on people - it was a joke some day, it is still a joke, but now it must be calculated for months ahead.
