BTE?
BTE is a coin meant to be a 1:1 clone of Bitcoin. Currently it is in a relatively quiet state (dormant, about 24 blocks in the past day
http://bte.cryptocoinexplorer.com/chain/Bytecoin) due to the long retarget time of 2016 blocks and the high current difficulty, but it is hoped for it to rise up again. A fork (switch to merged-mining, change difficulty retarget) has been proposed, but it is under consideration.
