He is PM forum members says he cracked Claymore miner and has a no fee mod that turns of fee and when you don't reply he keeps lowering price, I paid 0.1 bitcoin for xmas special which after paying he tried increasing cost to 0.3 but others have posted paying 1.5 bitcoin for software that does nothing, I opened a threat at zcash forum to warn others mine does not even restart miner but stops miner completely it's likely Claymore is on to him with latest release and blocked his hack and he's still selling anyway saying it's working with latest release
