Once again: Do not send your fpgas to them .....
Why trust them not to run with both (money and FPGA)?
They, should send ASIC first and after you have them working, you should send them the FPGA. They owe you that ....
I question whether people will be wise to ask if the deposit will be honored in BTC (not BTC to USD).
If so, that would be a very good thing.
