Be realistic. Bitcoin will have the same privacy level as DarkCoin once DarkWallet is finished.
It's Litecoin that has zero privacy. Thats why #2 place is realistic, if all turns out good. #1 not so much.
FYI: dark wallet alpha 4 is out. They are looking at deploying distributed nodes next. Will this be as good as MNs? I don't know. Darkcoin needs to roll out pronto if it wants to stay ahead.
I've played with Dark Wallet using real Bitcoins. I know it's alpha but it has spooked me not to play with real Bitcoins.
One time I lost $20 USD, and soon after their central server "unsystem" went down. Finally after 2 weeks, the system became available and spontaneously the money came into my wallet.
Then another time I was just playing with 50 cents worth using the stealth addresses from one computer to another. The money went to some unknown address not in my wallet. No big loss, but sure didn't help with building confidence in their product.
The CoinJoin feature only finds 1 other willing participant for mixing, not very taint worthy.
I'll be back when Dark Wallet finally reaches Beta but for now, it's only ready to play with in Testnet.
