cryptometh was launched march 04 by _Heisenberg_, an account registered on the same day as the launch with ID/Email information hidden. it used a Keccak/SHA3 proof of work and had an 0.9% premine amounting to a bit over 73 hours worth of mining rewards. Their reward halving was at intervals of nominally 180 days. After a smooth launch, they couldn't get listed on Bittrex because bittrex objected to the drug reference in the name. They were listed on allcrypt, but the price collapsed and miners abandoned the coin.
