IMO, ETH are very risky. a bug may be found, some regulation are incomming, need scaling and Im worried how it would scale.. ETH seems to me as a coin that may fork again, with which consequences ??
I think eth is incredibly risky, but not because of the tech, but because such a gigantic portion of all the available eth are getting into ICO's with zero value/zero product/zero customer's.
Rough estimate, this could probably be figured out, i'd guess 5million or more eth's are in ICO hands now, and there are only 93 million total right.
This is an insanse percentage held in a TINY number of hands, this doesn't even include the genesis block folks which also hold gigantic amounts.
This is a ticking bomb. If you bought eth high, over 200, any sane assesment has to include a very real possibility this thing goes to 50 bucks or less, and this is alot more real than a typical investment declining, this thing is incredibly dangerous.
Don't hold 1 dollar more than you can't loose tomorrow in eth, not right now.
