I always think why ETH can success (in price, at this moment) while BTS not yet (I still think it will success). Obviously the answer is ETH price go crazy. Then what is the reason for ETH price to go crazy? They got pretty good promotion strategy (I don't quite know in details, but they seems doing quite well in letting people knows 'ETH'). How promotion can be done so effectively? I don't know. But ETH mining does give a hand. I keep seeing the miner website cryptomining-blog promoting the ETH for free. BTS promotion is certainly a failure (no matter what they argue). If I remember correctly, they even pay a promotion delegate (the tri-fold leaflet... sigh).
