Apologies if this has been covered before, but what will happen if a batch if not completed (in a reasonable amount of time)? I'm asking since batch 6 begun on June 6 and, as far as I can see, only 643 chips have been paid for as of right now.
I've been curious about the slowdown in orders as well. My assumption is most people who were willing to take a risk & leap on faith on unproven Avalon chip delivery have mostly done so, and after batch 1 shows up many more orders will start to come in rapidly. There are also may more other group buys popping up, many of dubious quality it seems.
For the refund, I imagine steamboat would simply refund the BTC if needed. This is one reason why the group buy requires that you only send from an address that you control in your own wallet, makes refunding very easy.
