Isn't that similar to merged mining but much worse?¡¡ That's an attack.. there's no leveling at all!
I've been watching the situation. The share pool changes every minute. The pool is at https://coinex.pw/. Register there for your worker and password, and direct your miner to stratum+tcp://stratum.coinex.pw:9944
for SHA-256 coins.
It seems to put hashpower in the high profitable coins, and many people then dump the coins, bringing the buy price down and lowering the profitability. This seems to bring all the highest coins to a similar price --- it levels all the coins through the market.
I did place a buy order at a fairly high value yesterday, and made BTE one of the high return coins. It was in the rotation for several hours, then someone filled my order. The share pool's scheduler responded to an order of 1,000 coins. I did not try smaller orders.
But once they finish the profitable orders, they are gone leaving difficulty through the roof. Merged mining is constant, stable and solid.
