several things.
faith - of course.
Also,
Everyone know how paypal works, an how is chargebacks easy can be done there.
Go with paypal for scam is really bad idea,
my personal account was seized for 2 weaks, not funny at all i can admit,
for company i guess this even more harder;
now, about refunds, if they bought another 20k chips (don't know if it's true, but some one tracked transactions here at forum),
and they able to produce all in one batch, of course they will not be happy stay with assembled and unsold gear(yes yes, they can mine and so on, maybe they will at the end, who knows).
So finally, if there is 4 guys, and they need to organize all process of assembly from A to Z(pcb, soldering, cases, testing, etc) plus hosting.
i guess is not so easy, especially if you actually depend on chips delivery + 3d party pcb design.
If they doing that, so for me it's ok, even without nanosecond updates.
About @BBKCoins, cool guy!! At the end, if they will pay out royalty to BBKCoins from each board, will be perfect.
Maybe i dreaming, and cold reallity will punish me for that, but allow me to stay in that mood
Thanks
