I am all for this setup because they have an open day/house in different cities, they cover their own NRE, their hash rate is the cheapest in this industry and take orders when they have stocks coming in or available. 2 factors that they need is Time and Costs.
But where are the chip specs, design informations, etc. ? I think that we've seen too many scams on this forum to do the same mistakes all over again.
The only good thing so far is that they are not taking orders without stock IMO.
