As of recent 10 days or so, Ethereum (ETH) has taken over the lead.
It is most likely temporary, as it has not fundamental reasons to continue, but right now, the big money first moves the ETH market, then btc follows.
Today we could have seen a big candle down in btc from 3532 to 3405 (wick). That candle ended up being green on BTC. The same candle on ETH ended up red.
And see where it went.
It's a small trade trick that currently works, so why not use an extra edge as we are waiting for Blockchain Whispers 2.0 :)
I expect Blockchain Whispers 2.0 to be released some time next week (we are shooting for Tuesday!)
