What did you do with it?  Your auction specifically says it is lightly used, but was not mined with. 

I doubt you were suspended for selling an ant miner.  Ebay verifies everyone that sells with them.  Most people do it via a bank account.  If you don't link a bank account and\or answer their profile questions, they ask for photo id (here in the USA anyways, this isn't all that different than what a pawn shop is supposed to do). 
It isn't bitcoin mining equipment per say that they consider high risk but computer equipment in general.  You would get the same shit if you were trying to sell a laptop.  With that said their customer service is pretty terrible, and completely random.  I sold a lot of stuff with them but they refused to let me sell one particular computer part (I don't remember what it was, maybe a RES?) even after I provided them a receipt.   I guess they thought it odd that someone would have several of them. 

I guess we will have to agree to disagree then.  I think it is very obvious they want to be in the mining business.  They didn't build a cloud mining center just to test these things.  They could have picked any microprocessor industry they wanted to and they picked this one?  Why would they pick Scrypt ASICS if they didn't want to get into mining? 
I think your answer demonstrates a fundamental misconception about how this industry operates.  NONE of these ASIC manufacturers are in this business of  selling miners to customers.  None of them.  When bitcoin (and now Litecoin) became valuable enough for large scale mining operations to be profitable, a number of companies saw the potential of building purpose built machines for mining.  The idea of selling preorders to customers is simply a means of financing that leaves the company with an interest free loan from people who have no claim on their assets and no oversight (banks and venture capitalists demand things like transparency, oversight, risk management, you know, all the things that customers complain about but agree to do without anyway)  Trust me, if these things retained their value at all you would never get anything, they would just refund you.  As it is, with these things losing their value so quickly, it provides them with a great interest free loan, and then a place to dump off their old products when they don't need them anymore.  Meanwhile, people like you think you are an actual [valued] customer and can't imagine why they treat you like crap.  Never realizing that they never wanted customers in the first place.  And besides, they don't have to treat anyone nicely.  They can treat you like complete garbage and still get, what was it you called it?  The benefit of the doubt. 

Anyways, I guess there isn't really anything left to say about this company.  To all who ordered from them, I wish you the best of luck.  Hopefully you didn't lose too much money when the dust settles.  I guess the good news for people who like to throw their money away, GAW just announced their preorders for fourth quarter.  So I'm sure we will be having this exact same discussion again soon. 

How is it a stretch at all?  We know they are miners.  They have said as much.  We also know that if by some miracle they can pull this off, they will for a very very short period of time have in their hands the most powerful miner on the market.  You honestly believe they are going to leave millions of dollars on the table and ship those miners to their customers?  Really?  Bearing in mind that the contract with their customers specifically states that there is NO guaranteed delivery date and they can deliver whenever they want, or not at all (essentially refunding instead)?  Put another way, say YOU had a couple hundred 250Mh/s miners right now.  Would you really head down to Fed Ex tomorrow and ship them off, or would you wait a while, make some money, and THEN sell them?  All due respect, I think it is very naive to think they would leave all that money on the table.  I only mentioned other companies because to date, no company has picked their customers over themselves when placed in that position.  So it seems to me a bit like a little kid who has stuck his finger in every electrical outlet in the house but he is going to do it one last time because hey, this outlet may be different.  

But the question still stands.  What has this particular company done differently that makes you think this is going to turn out better for the customers than all the other preorders before it?

Oh.  It sounds like they are trying to rob you tbh.  If someone or a website owes you bitcoins there is no need for them to send you any files, they can just send you the bitcoins. 

I guess I don't know what your point is?  You made a list of pros and then argued against them but no one said them in the first place.  Typically in a debate one lets the other person speak, and then attempts to refute what they say.  Not invent the other person's argument for them and then refute the imaginary argument. 

With that said, replacing fiat "bank credit system" with bitcoin will never happen, and one only has to look at your first point to see why.  Your first made up argument is that bitcoin is better than fiat printed by the bank.  This may be true for you or me, but is obviously not true for the bank doing the printing! 

Why not just ask the person who sent it to you what it is?  Why ask us?

Simple rule, if it isn't in stock shipping now, then don't trust them.  Follow that rule and you'll do okay, at least you won't lose too much money.  The stuff shipping, most of that will not mine what it costs to buy.  You can see this with the tiered shipping models some of them use.  Like what I mean is, they sell it this week for 2500USD.  Next week it sells for 2000USD.  The following week 1500USD, etc but it mines way less than 500USD a week so you make more money (or rather, lose less money) just by doing nothing.
That said, the best all around scrypt miner on the market now is still the Gridseed blade and you can purchase them used at prices that will ROI, you just have to look around.  The innosilicon terminators are actually really nice, but it is unlikely you will find one selling for less than it will mine.  

Buying used is the only way to get these things at decent prices (and none of them come with warranties worth a damn anyways so that isn't an issue) but if you insist on buying "new" Zoomhash is good.  If they say it will ship today, it will ship today, etc.  GAW is okay.  Ive never had anything ship on time with them.  If you harass them enough they will eventually give a tracking number and say they shipped it already and then like 3 days later it will actually ship.  On the other hand they have always given me compensation worth more then what I would have mined anyways so I can recommend them. 

Its About Sharing,

The thing is all those things you mentioned were promised in the original deal that customers payed for.  It would be a little like paying an extra 5k to have leather seats in your car, then you go to take delivery and the seats are cloth, and the sales guy tries to tell you how cloth is better cause you won't burn yourself on a hot day (but of course won't give back the 5 grand). 

You like to ask questions, so here is one for you.  Why do you think this is going to turn out well?  It is obvious to anyone that doesn't have stake in this company that they will not be completed on schedule.  And even if it is, do you really think they are going to send it to you?  They are very open about also building a cloud mining operation.  Do you really think they are going to give you machines first and then themselves?  Given that they have no contractual delivery date with you can deliver whenever they feel like it, or not at all?

It isn't like this company came along and said they know how preorders have gone in the past and they wanted to do it different, and then did things different.  This preorder has gone so far exactly like every other proerder ever, and we all know how those turned out for customers.  So my question to you is, given that they have done things exactly the same, why do you think this will somehow turn out different for customers?

Very insightful.  Mine profitable coins, unless they aren't profitable.  Thanks for the tip!

They claim as of yesterday that they are still on schedule for shipping in July.  But as you mentioned, they do not have working prototpye yet.  In fact from the update yesterday, they don't even have the chips yet.  So clearly they will not be shipping anytime in July.
They also do NOT accept credit cards.  They keep promising to add this, but as of yet they have not convinced the bank to allow it.  As you yourself pointed out a company has to be legit to convince the bank so that should tell you everything you need to know right there.  My guess is the bank took one look at their business model and said no because they realized this is going to be a million chargebacks.
Lastly regarding the refunds, they promise partial refund (which in and of itself is illegal) but I do not know of anyone who has actually gotten any money back from them despite trying.  Actually, I do not know of anyone who has even gotten a response from them once they mentioned refund.

Anyways, where does that leave you?  Well you're obviously not going to be getting a machine from them in a timely fashion.  Your best bet would be to get a refund, but they don't seem to be honoring refund requests.  I think your best bet is to just convert it to a 50Mh/s.  Yes you lose the difference but you already lost that the day you bought this preorder, thats gone and not coming back anyway.  This way you don't have to send them any more money and eventually you might get something.  It will be worth a fraction of what you paid for it of course but hey something is better than nothing.  Basically any option that doesn't involve you sending them more money is the best option.

First, the last block will be mined many many years from now, no need to worry about that just yet. 
Second, the price of bitcoin has a lot less to do with it than you would think.  The big mining operations aren't going to just shut down.  The mining rigs are a sunk cost, they won't turn them off just because they are making less money.  Sure they may look to sell some machines, but only people who would buy them would be people who were going to mine with them anyway so that doesn't reduce difficulty.  Besides, bitcoin would have to drop to like, 50 bucks for it to cost more to run the machines then they make and even then they may still mine, hoping for a price increase later.  At most, you would see them cease or reduce development of new machines so the difficulty stays the same, but it wouldn't go down.  In any case though most of their R&D costs are born by "customers" who preorder their miners so that isn't much of an issue. 

There is pretty much no scenario that could happen that would both cause the major companies (the ones driving the difficulty) to want to shut down while at the same time, ordinary people would want to still mine.

I used Ognasty (I was the buyer) and things went smoothly.

Where to even begin?

1.  Dev's job is to make a good coin.  Dev's job is NOT to make sure you personally can profit from mining a coin, or that it be worth a certain value. 
2.  Even so, the coin is at it's highest value YTD what are you complaining about?
3.  The coin did not lose 40% of it's value.  The coin was very temporarily and artificially inflated in price because while people could buy as much as they wanted, those holding coins couldn't get them on the exchange to sell. 
4.  He just came out with major changes and a new wallet (incidentally, you want him to do things but doing things is what caused this in the first place); that isn't "abandoning" the coin.

Listen, if you were paying attention at all you would have known it was only listed on one exchange and that the exchange wasn't accepting deposits.  Common sense could have told you that the brief run up in price was not real.  If that wasn't enough, you've spent the last two weeks bragging to anyone on here that would listen about how much better at mining you were than everyone else, what a genius you are at picking coins, etc.  Perhaps you will learn from this, and next time you see a well known coin with a much higher return than average, ask yourself why no one else is jumping all over it.  Or you could just blame other people for your mistakes.  I guess that works too.

Fact is, you fucked up.  You used the wrong numbers, your autoswitcher used the wrong numbers, YOU fucked up and mined the wrong thing.  Not the dev.  Smarten up. 

So they posted their update.  Few thoughts I had while reading it....

"At this moment there is a lot of tweaking and preparation while we wait for the chips as such there isn’t much to show yet."
So they don't have the chips yet.

"[about the payment processor]rest assured we are committed to it so it will happen but some things are just outside of our control. As soon as it’s up we will email you and we guarantee it will be before July"
This is why their word is worthless.  If it is outside your control, how can you possibly guarantee when it will be ready?  If it is something you have control over and thus can guarantee, why lie and say it isn't something you have control over?

"Reselling & third party buying

For now we do not allow orders to be resold and do not acknowledge the reselling of that order if it were to happen. We cannot and do not ‘transfer’ orders from one of our customers to another party. Orders can only be kept with the party that accepted our terms."

Really?  All the questions surrounding your business and your progress and THAT is what you choose to respond to?

Well yea your sure because it doesn't cost you anything if your wrong.  Obviously though and I'm sure you can agree, there is a huge difference in the value of your contracts if you start in one month versus two months versus 3 months. 
Explain exactly why someone who was considering purchasing one of your contracts wouldn't be better off just waiting until they are actually available?

I found many blocks. 

Some people would say that not buying it at all would be another option.
