People with their finances in order don't leave large amounts sitting doing fuck all when it should be earning interest or working for them no matter what that ignoramus just said.
most previous customers have mined more than 10BTC.. many well over that. Many have kept their BTC in a wallet as BTC itself was 'working for them' or at least still $$ in an exchange so they can easily buy back BTC when need be.
On your other point, you really wanted them to basically call up everyone one by one on the modules?? how long would that take? Everyone was already a bit mad that they waited to make a few more and ship all at once instead of just ship what they had right away.
3 days on the Neptunes showed that KNC priced it a bit better than the modules so they didn't short change themselves. If they were $8000 they would of sold out in 10 mins
