All anyone can talk about is the confidential transaction ability of XMR, WBB V5, BTS Stealth Transactions, Zero-cash etc, and none of them even have a GUI yet.
The question is, how high will confidential transaction coins fly once their GUI applications come out?
AND WHICH WILL BE RELEASED FIRST?
I do not think the release their GUI will affect the price that much. It will for sure help make the coin easier to use bringing in more users but that is it. The price rise would depend on how much the whales pump it and how many ordinary people join in with the ongoing hype.
