Are people seriously trying to argue there hasn't been a dip? That's not even worth responding to, of course the wallet release affected the price. If you feel otherwise, it's not worth trying to explain to you why you're wrong, because you're either trolling or just stubborn.
Whether the price will go any further down - that depends on this rumor about not all ICO coins being released yet. What we need is a clear statement from the ETN team about what the mined supply is, what the ICO supply was, and how much of that ICO supply has been moved out of the ICO wallets. It should be in the ETN team's interest to be transparent, as that is what will give value in the long run. If they cover up facts and figures to protect the short term price, they will hurt the coin long-term.
there HAS been a dip. from 11-13 cents to 7 cents, it just wasn't as severe as most people expected. I personally don't think that there's a lot of people who can't access their coins yet (maybe less than 10%). Although it seems like there is no way to figure this out from ETN/Monero blockchain as it's very secretive/privacy oriented. It would be nice if we could hear an official statement about how much of the ICO coins have been successfully accessed. So that those who still expect a deeper dip can get over themselves and we can proceed to the moon.
