Since Ethereum "Time Travel" hard forked away from Ethereum "Classic" the total mining interest in the two chains is down ten percent. Similarly
ten twenty percent of the mining interest in the Buterin blessed1 chain featuring a time-travel hard fork attack to "undo" the whole DAO episode appears to have moved to the Classic chain. Mircea Popescu published a guide to pricing the various forks of the original Ethereum scam coin this morning.
At the point Ethereum forked it was still very much like its predecessors Dogecoin and Litecoin in being of little utility beyond service as a vehicle for disposing of actual forms of money. Like those two, Ethereum has Buterin while Litecoin had Charles Lee and the Dogecoin had Jackson Palmer and Alex Green/Moolah.io serving as their chiefs of inviting the herd to tour the woodchipper. Thanks to the passage of time blessing it with a history, Bitcoin is unlike its alternatives in many ways2 that make projecting their fork experience on to Bitcoin untenable. Sorry fork, your loss.
This is the other reason why you can't have Altcoins. Any Altcoin is going to be far too new to develop the adversarial relationships between various interests that protect the chain. ↩
