how far in terms of price it can go?

$100 easily, reminds me of the legendary blackcoin pump

CMC claims there is 89,833,923 coins, where did the other 10 million come from?

That was clearly rounded, the point is that the value of Ethereum can never come close to that of Bitcoin because there are far more coins.  This changes the way that we should look at Ethereum because the only relevant thing we should consider about Ethereum is its market cap, not its price.

Our Position on the Possible Hard Fork

As stated in the recently-published hard fork contingency plan, Poloniex agrees that any contentious hard fork must include replay attack protection. Without this, exchanges cannot continuously and properly operate.
Why can’t we pause markets until a "winner" emerges?

Unlike a planned fork where the block height is known, Bitcoin Unlimited can activate at an unknown date and time; therefore it is not possible to plan for such an event.
Are you going to support Bitcoin Unlimited or Bitcoin Core?

We will support Bitcoin Core continuously as BTC. In line with our current internal policy, if you have Bitcoin on balance at the time of the fork, we will make Bitcoin Unlimited available for withdrawal provided it is safe to do so. At a minimum, any new fork must include built-in replay protection. Without replay protection, we would be unable to preserve customers' Bitcoin Unlimited without halting Bitcoin withdrawals, which is unfeasible.

At this time, we have not determined whether or not we will be listing Bitcoin Unlimited.



hmmm, could be ETH vs etc on a bigger scale,  btc vs btcu
 maybe have some fun with BTC....im in the unlimited camp (for the time being lol)  
a major alt dump could happen anytime soon as peeps try to hold btc in the hope of gettin free btcu

What is the best option to locally store ETH coins? Is there anything like electrum?
