Today the Syan Mining website is down.  I think that pretty much settles it.  Wow, I sure learned this lesson the hard way.  But still getting your hands on miners (as in bulk miners over 60 units) isn't very easy now.

Between miner companies being outright fake and others selling product many months before they can deliver, it seems buying Bitcoin miners is a minefield of unknowns.  A miner is something that has a short shelf life, potentially, such that getting it late could cause one to not even break even.  Companies should not only provide escrow but also escrow with an delivery expiration.  Why?  Because if I order from Bitmain, for example, today and they take until May but I could have ordered say from Canaan and got the product the end of March (or vice versa), that matters a lot in mining.  In fact it might be all that matters in some extreme cases.
