with shadowsend v2 I'm surprised we are not already at $1+
It is most probably the best anon in crypto today. (why mince my words? it is the best)
perhaps after the next hard fork we will be.

this project is ambitious and gaining momentum rapidly. if the market is running smoothly (later in the year) and has growing adoption numbers then that'll be huge.

shadowsend v3, which will likely come later this year (pure speculation on my part) would for me (a privacy advocate) be just as big a deal, if not bigger.
shadowchat will be dramatically improved. shadowmarket relies on shadowchat.
voip functionality and file uploads will almost certainly be included at some point in the future
features like i2p torrents on the shadow network would be amazing and are realistically achievable. More developers are coming on-board and talk of api's/sdk's is very exciting; building a platform for other  developers to build apps (that's how i understand  it anyway - pls correct me if wrong)

The promo video (see above) is a powerful encapsulation of this vision. And this Team (and future developers) WILL make it happen.

Therefor in the coming months (by Jan 2016 and assuming continued confidence in BTC) I think $5-$20 a coin is quite possible. I expect $1-$3 much sooner.

oh, and i think the android wallets will blow people's minds. sending shadowsend (anonymous) transactions from a phone will be a game-changer imo. not to mention shadowchat on a phone.
