If bitcoin dies something like ethereum won't lead the way forward? I think steem could survive the death of bitcoin.

At this point in the game, I don't think so.
If BitCoin dies, the rest of the cryptocurrency market dies with it.
If one of the other cryptos was in the position to be the crypto-savior without BitCoin, it would have a 6 month high right now.

It seemed like ethereum had gained on bitcoin although ethereum did really tank lately even more than bitcoin.
