So, to reiterate something I've said before - how long do you wait?  You say 2 weeks after the chips arrive, but that's meaningless.  What if the chips never arrive?
Are you going to just wait forever, and if they never show up, continue to defend it by saying well he still hasn't missed his deadline?  If not, how long is long enough?

I already firmly believe the chips will never show up.  Yifu's explanations don't add up.  There's too many indications that something is going on that Bitsyncom doesn't want anyone knowing, and it's not good.
You're entitled to sit and wait if you like, and I'm not going to say otherwise, nor will I tell you you're wrong to do so.  It's your money it's your choice.
I'm not willing to become a passthrough victim to Bitsyncom's scam, that's the bottom line.

But just to satisfy those who are nitpicking on my comparison due to size, fine.
Let's say you go to the small time local electronics shop down the road.  They're advertising a super high power LED flashlight you think is cool, and taking pre-orders for it.
You preorder one and pay in full up front.  They say it'll be delivered 2 weeks after they get the LEDs from some other company that already has a less than stellar reputation and some concern about whether they're entirely on the up and up, or maybe just enough to keep people coming back for a bit longer
Are you seriously telling me that if something went sideways and they didn't get their parts; they couldn't tell you when they'd get the parts other than they were 'pretty confident they'll start shipping the parts to us soon'; that you'd just be content to sit and wait?  That you'd be content to lose your money if those LEDs never came in?

If that's really what you're saying, you are the wet dream of scammers and dishonest cheating corporations everywhere. (not saying that all businesses and corporations are dishonest and cheating, just the ones that are)
