g_d :   Just a theory... One of the guys they work with, has a company that makes mining hardware. so its a logical possibility that they don't care of you mine it or not and even more it might be a possibility that they mine and sell most of the coins out there(without a need to touch the premine)  

combine it with with the fact that currently(as i'm writing it and it might change)  http://www.israchange.co.il/  - says that they sell each ISR for 0.10 sekels which is about 0.03 cent (a lot more than the price in crypto exchanges) plus offer "discount" to whoever buys in bulk...

I will not be surprised if the coins that they sell in this site and also the coins sold in "change stores" are not getting bought off exchanges and are being sold from the amount of coins that they mine everyday - if they partner with a mining hardware company then again its possible that they produce a large amount of coins everyday (not saying that its like this, just saying I won't be surprised).

And even in THEORY _IF_ they are buying it off exchanges.. they would actually enjoy a "low" price because they sell their ISR for a fixed(and currently higher) price at http://www.israchange.co.il

So why should they give us any word? they might not even need us.

P.S - the housing deal from the link posted above says that you can pay with ISR up to something like 14,000 sekels which is something like 3700$ - and of course there is no evidence saying that they accept ISR at a higher rate than in exchanges anyway.
