Maybe the trust of a bitcoin bank lies in price stability too and for now i can't imagine people loaning bitcoins from a bank. So why keep them at a bank when you can keep them on a usb stick or 5 to make sure you still got them if 1 fails.
I mine for some time on this pool and i get a lot of difficulty fluctuations but on the pool site everything is ok. I get shares and when i look at the block stats i see that i get said for every block. Maybe it's a cgminer problem not showing accepted shares because they get solved too fast. And for people getting to many rejects try tweaking your intensity. I have 2x 7950 sapphire oc at 1050 with 5800(~1470 mhz) and i get ~20-25 %rejects at ~600-620 kh/s at intensity 20. But with intensity 18 and same oc i get 580-600 kh/s with 3-4% rejects. Hope i can help some of you.
I don`t think wdc is just a pump and dump. dgc is ahead because it survived the pump and dump. Besides wdc is pretty stable at the moment and i hope they both survive.
