Around 700 000 coins still to dump. As long as the prices don't go up it's only $7000 ( < 0.8 btc) worth of coins. Don't push the price up and soak the dumps, easy money.
Can you explain why dumping will stop after SIGMA, won't the new miners sell coins?
When SIGMA is released I will become a miner, I won't sell coins at this price and many users will save or use to contribute to witnessing to earn more coins. Dump pools mine NLG and then send to the exchanges to dump, they don't care if price is $0000.1 or $10000
