Real coin will be shunned by most of the "Coin" community, seeing as it is a filthy way of riding off the crypto idea. As the the general populace... We must educate them. Now.
Price stability means nothing. It's because some companies want to take it and possibly hold it for bigger profits in the future, or they're taking the risk and just accepting Bitcoin for what it is.
Realcoin actually disgusts me. It's a scheme, and it's just like using a credit card or debit card at a location. We can defeat it by saying that it's just like your credit card but with more and longer complex steps. That would be enough to have people ever away from it.
And then they beg it to Bitcoin as well as the USD, if I read it correctly. So if USD thanks, "Oh nope! Our value is backed by Bitcoin!" (In which case, if realcoin does become popularised, would be great for the BTC price. We own the gold of the future!)
But I have serious doubts about realcoin... I wanna see the code, since there might be "unprecedented security flaws" and it might "just happens to be possible to find the IP of an address".
Realcoin will never be successful because it's network will never be able to be secured. Like bitcoin TX fees for realcoin will not be enough to give miners enough of an incentive to mine at first, however block subsidies will obviously not be given as the coins are backed by dollars and block subsidies would mean that someone would need to pay dollars to secure the blockchain
