From a business point of view it does not make sense to sell a product that is 28 x more powerful than your last product and 9 times the power of your competitors latest release (4 x cubes joined). If it is a money making exercise then you might offer a 2.4GH/s, then release a 4.8GH/s then a 7.6gh/s then a 10.8gh/s. Sell 500 units of each at $5000 and you have made 10 million dollars. Or jump straight to 10.8GH/S, sell 500 and drive up network hashrate 2x or 3x the current global hash rate in one release where your product becomes ordinary really quickly and only make 2.5mill.
I'm not sure that your analysis works with Chinese companies. If they can get money right now - they will do it, before their manufacturing facility will be caught of safety issues, poor treatment of workers, illegal usage of IPs etc
Fast make + fast sell = mega profit (can buy condo on Maui)
Bitmain is a prime example, a chinese company thats building miners like toasters and is selling them, but why not mine it all for themselves? Because its more lucrative to do both. God help us if they produce a x11 miner. They prob wont because dash hasnt got the trading volume of something like btc. If ibelink mine on even 1/4 of what their first batch will apparently do then thats a lot of dash coins a day sold on market to make instant cash, dash trading volume isnt high enough to probably absorb such selling, without probably decreasing the price, and even if they hold the mined coin theres no guarantee theyd be able to sell it in the future for as much or more. Dash is still a late bloomer and its price is still prone to volatility. No Company wants to fully crash the market they're in business with. By only selling the dm11g to major players at least they know that those people are more likely sophisticated investors who wont sell in a panic or in a way that will ruin the price, unlike say like a amateur home trader/miner would do. Thats why its going to be so difficult for any average person to get their hands on this equipment, because in the wrong hands it could destroy the marketplace in enough numbers, and the resellers that do sell it are only going to sell the machine with a huge markup because its the best thing going and blows away the competition. Anyone taking the risk of pre ordering this machine is doing so at a huge discount on what resellers will charge, and even once ibelink sell them to everyday consumers they will pay more for it and cop the difficulty increases that will follow (mainly from further batches and new megaminers the competition might dish out later). Every week will be crucial in ROI and only the first batch owners will make a killing, and even if they dont, they could sell the miner for a premium to the customers waiting to buy the 2nd batch, which could be another few months, if that even gets sold to the general public.
