I think difficulty has increased very significantly that mining isn't as great as it was a few days ago, so I'm not too worried of a huge dump. Also a ton dropped on the first wave and goes to show that whales have already made great profit and are getting out because they don't want to lose anything.

I think it probably will increase more, especially if it starts hitting exchanges. There will be lows and highs at times, my guess is that it will be at $0.25 and followed by a dump, might drop back to $0.15, then it will increase further probably to $0.35-$0.50, followed by another dump. After that we might see it going up to $1 by next year, this might be after 100th block and PoS.

We just passed the 0.15-0.16 dump and it looks to be recovering, for now.

I don't think it will ever be lower than $0.05.

This theory depends on value of Bitcoin as well, because if Bitcoin and all cryptos drop for whatever reason, so will SIGT.
