Concerning Reddcoin, I don't think there will be major dumping on August 2nd. The manipulators can't compete with a sudden change to the coin supply.
Miners are presently dumping 18 million coins per day on Reddcoin, but on august 2nd, all that dumping will end because of POSV.
And from august 2nd, POSV will only create 1.2 to 1.5 million coins per day. Now compare that to 18 million from before.
If Redd is to follow the same pattern of previous coins that went through such a transition, we could see the price reach 333 to maybe even 5000 satoshi.
