Seems to be more like 25% right?
( at least on ETH/BTC market.) Despite not holding any ETH, I actually traded it a bit for a while. On quick look it seems to me that 0.01 held nicely for more than a month, so seems like a decent bottom.
Then generally with alt coins there just need some random news for it to pump a bit. I personally don't believe that it is very rational that the "
Enterprise Ethereum Alliance" would somehow make the ETH market bigger. Simply because "
Enterprise Ethereum Alliance" is going to use
private Ethereum blockchains, just like R3 was planning to do (but eventually didn't.) Therefor there won't be any new money coming in based on that news. You can spin it a bit and say "
but it is a good sign that blabla..", but really a private copy of Ethereum isn't new money into the market (as it has nothing to do with ETH the currency.) But speculators gonna speculate, so I have no doubt that this news "triggered" speculators to buy some more.
(edit: to be clear, alt coin traders/speculators I don't consider as "new money" despite that it is obviously rising the price - at least short-term.)
