The same exact people who are buying them now I assume.  Not really sure why that would change.  At one point I wondered why people would continue to buy shitcoins that were obviously going nowhere, ever, but then, I also thought the same thing about preorders and yet here we are 

Um, this isn't a sports betting thing.  EVERY game you play is distorted to give the house an advantage.  Where do you think that 3% you mentioned goes in roulette, which would otherwise be a break even game?  Bitcoin doesn't change sports betting in the way you think it does.  After all, you can already do peer to peer betting with FIAT, you don't need bitcoin to do that.  Say you and I place a wager with bitcoin.  I lose.  How are you going to make me pay?  Oh, some third party is going to hold the money for us and pay to the winner?  Well they won't do that for free.  Enter the vigorish.  Now granted it may be cheaper, but it is still there.  And of course such third parties typically provide other services as well such as credit....
Anyways, that is getting off topic.  Bitcoin doesn't really change gambling at all.  What bitcoin DOES do is as someone else mentioned, allows anyone of us to House games.  That's really the only thing They care about.  For all the talk about how gambling is bad, blah blah blah and gambling is illegal here in the USA, the biggest gambling operations are all run by the state.  I can go to any convenience store and purchase tickets in the state run numbers game, drive two hours in literally any direction and be in a legal state sanctioned casino....etc.  Like most things involving bitcoin, they don't care about bitcoin itself, or even what is being transacted, they just care that they won't get their cut.

There is no set of circumstances where paying 1 btc now to get some amount less then 1 btc later is ever good business sense, barring some very rare and unique situations.  Yes, playing tricks with exchange rates you can kid yourself into thinking you made a profit but it is always a bad business decision. If I buy btc with my 100USD, and you buy contracts (that will yield less total btc) than at the end of the day I will have more btc than you.  BTC could rise to 1000USD like you said, I'll still have more money than you.  The only situation where buying mining contracts could be considered profitable is if they pay out more than they cost.  But they pretty much never do, which makes them a stupid investment. 
They aren't anything at all like futures contracts.  A much better comparison would be to consider them some sort of bond\loan.  With a bond, you have to decide if you want the certainty of the money remaining constant, or are willing to risk a loss to possibly make a gain.  But BTC contracts are like bonds with negative interest rates.  Who in their right mind would give someone 100 dollars now to get paid back 75 dollars later on?  It makes no difference if the purchasing power of the dollar rises, it was still a bad decision. 
And lastly, about the contracts paying off when the difficulty rises slower.  Naturally they would charge a substantial premium during those times.  What you are basically betting on there is that you are better than they are at predicting difficulty increases which seems.....very unlikely.  And even if you are, these things are so heavily padded with profit in their favor they would have to be WAY off for that to work out in your favor.

Tldr, paying 1BTC now to get back .75BTC later is always a bad idea. 

Thanks, that explains the lack of a payout.  But what I am concerned about is that I have coins stuck in immature, and unexchanged.  They have been stuck there since this all began about a week ago.  I should clarify, I stopped mining on the site when I noticed this and was waiting for them to catch up with processing before I mined some more.  But now a week later and my coins are still immature and unexchanged.  Sorry to post this here just I didn't see a contact or support button on the website either.

It says daily payouts, but I have not receive my payout in 5 days.  Any reason for this?  I still have coins stuck in all four stages (immature, unexchanged, etc) and the numbers have no changed at all in almost a week. 

I've placed a number of orders with these guys and never had any problems at all.  They always responded to my messages right away, and every thing I ordered got to me sooner then they said it would.  I don't do all my purchases there because they don't always have everything I want, but I always check them first just because I trust them to actually deliver what they promise, when they promise.  That's been my experience anyway. 

He's also a self entitled douche, so there's that.  Incidentally, what you say may in fact be true, but I find it hard to believe someone that experienced doesn't seem to know how a multiport works. 

I'm guessing their design was just messed up.  Consider, One of their 1.3Mh/s units was originally slated to do 1Mh/s at 12 watts, at 280Mhz.  The finished product does 1.3Mh/s at 328Mhz and consumes 45ish watts.  Underclocking it to 280Mhz or even lower does, at least in my experiments, virtually nothing to reduce power consumption (maybe 1 watt).  Of course undervolting it would reduce consumption but I have to assume they tried that and were not able to get it stable at anywhere near 1Mh/s, or else they would have done that to begin with. 
Of course, this is the Zeus machines, but the Hashra devices are using the same chips just in different multiples, so outside of 1-2 percent differences they have the exact same issue. 

I am not sure what you are asking.  Are you asking if renting a rig will lose money?  Well yes of course it will, barring some unusual set of circumstances.  If I have mining equipment that will mine say, 1BTC per day, I'm not going to rent it to you unless you give me MORE that 1BTC per day right? 

I took one of the Zeus 1.3Mh/s machines down to stock speed of 280mhz (the default OC is 328 I believe) and it was still pulling 50 watts from the wall on a platinum PSU.  Consider that 8 gridseed blades pull 737 watts from the wall on the same PSU yet will do 45.6Mh/z at 838mhz and you see the problem.  What would it take on one of these things, around 1600ish from the wall to get similar performance?  It isn't a clock issue, or a firmware issue, or a configuration issue the chips in these things simply pull way too much power.  There is no way around that. 

They aren't the only ones selling the A2 machines, in any case.

Blades don't use anywhere near that much power despite what they say on the website and the box. They pull about 90ish watts from the wall (total, for both panels).  On a per Mh/s basis, they use about twice as much as the A2 machines, and half as much as the Zeus machines.  
Really the Hashra machines are not impressive at all.  They use a ridiculous amount of power, and who knows when you will actually get them.  They are a bit cheaper though so there is that.  Even so though, here in the USA you can't even run one on a standard household AC circuit.  Which means you have to host them, which means they aren't actually cheaper.  

PM sent.

Well the innosilicon machines became available in the US mid to late May for 11k each.  At the time they had no competition other then the Gridseeds.  Since that time Zeus, Hashra, GAW have all released much cheaper miners.  Difficulty is now twice what it was then.  And we're a month and a half closer to the real big miners coming out (KNC for instance.  It is likely that at least one of the big miners will actually come to market and of course it doesn't have to be released to customers for it to kill difficulty). 
Realistically, based on difficulty alone they should be selling for half what they were on release.  And yet they are still full price. 
Please note I realize this is probably not something you have much control over, innosilicon charges what they charge.  But since you asked....

More importantly, the prices are the same as they were a month and a half ago.  But obviously the machines aren't worth as much as they were a month and a half ago. 

What sort of price are you looking to get?

Generally speaking federal law always trumps state law, except in cases where the federal government decides not to pursue the matter, as in the cases you mentioned.  The US Supreme court has ruled consistently that the federal government has the authority to control drug use in the states if it chooses to (not withstanding the fact that any "common reading" of the Constitution fails to turn up any authority to do so).  I can't off the top of my head think of a single case where the courts ruled that state law superseded federal law.  And given that it is Federal court that makes such rulings, it seems unlikely that they would ever rule against themselves.   In the drug situations you mentioned, the federal government decided not to pursue enforcement of those laws in those states.  The laws are still there though and who knows when or if they might choose to enforce them later.  In any case though these are two completely incomparable things.  In the case of drugs, the federal ban makes the default position, possession is illegal.  The state laws you mention attempt to reverse that position and make it legal.  In this case, we are talking about something that is already legal.  You can use bitcoin all you want in the state of California already.  They would have to pass a law that actually did something for any of this to matter, and if they were to do so and anyone were to challenge it, a "common reading" of the Constitution easily turns up evidence that they do not have the authority to decide what is and isn't money.  

What?  This isn't true at all.  Some guy walks up to you, puts a gun in your face and demands your wallet.  The police don't contact some special financial crimes department to investigate because it involves money.  Where are you getting this from?  And what does a debt collection agency have to do with anything?  

In any case as I tried to mention earlier the US Constitution specifically grants the US Congress the power to establish currency.  The state of California does not have any legal jurisdiction here whatsoever.  They can pass whatever law they want, it doesn't actually mean anything.  

I'm not really sure what this means, or rather, if it means anything at all.  I'm not an attorney nor do I play one on the internet, but as far as I know US citizens, including those in California, do not need permission from the state of California to use bitcoin.  So it would be a little like California passing a law that says it's legal to watch TV.  That's nice and all but doesn't really mean anything as you could already do that anyway (actually, if I were a citizen of California I would be somewhat concerned that the state thinks the default position is something is illegal until they grant permission but that is a topic for another day).  
What would be useful for tax purposes at least would be if it was declared actual currency, but then the state of California does not have the authority to do that (the US Constitution is very specific, and the Supreme Court has consistently ruled, that only Congress can do that).  

No one here has to prove anything.  Last I checked, he wasn't asking you for 4.2 million dollars.  You're asking for 4.2 million dollars with no strings attached, no contract guaranteeing delivery, no nothing, and the only thing you can do to respond to that is attach the people who question it, and make ridiculous claims about our ulterior motives.  At least the bums on the street who ask for free money don't pretend they will eventually pay it back.
