Quez,
Something seems to be brewing. I can't really put a finger to it but past weeks have seen some big volume at CCEX and Trex.
GRC are changing hands, that's for certain...
I know. I just wonder who sold nearly 30 BTC of GRC in this small timeframe when we had >30 BTC volume. But for 600 Satoshis I would have sold a bit, too

Probably one big investor bought for the 600 sats.
