Also, there's another problem with DRK in a sense that everyone thinks that it will be the greatest thing that happened to the dark markets. Dark markets are being shut down not because of BTC's semi-anon technology, but because they are still requiring trust. If you are trading real objects ( drugs, hdd's etc) and not virtual ones, then you will have to specify an address for delivery (duh!). Guess how easy it is for FEDS to participate in these markets, posing as drug dealers or anything else (duh!). Show me a story where the FBI managed to destroy dark markets because of the BTC's inferior anon protocol.
I've been thinking of getting an anonymous PO Box, and I'm not involved in any illegalities. I'd figure a lot of people ordering stuff they shouldn't would use such protection.
Although this is the greatest altcoin, my opinion is that it should get a name change and start being marketed as a currency that has the option for anonymity if necessary and not as "Darkcoin", which links directly to the dark markets. This way it would have more success to the general public. Not to mention that it could get even more traction because of the InstantX technology.
I'm thinking that maybe there could be another wallet with another branding, but still using the same blockchain. So you'd have "iCoin" (*) wallet with different graphics and all, and the coins would be called iCoins, the user wouldn't even see the name Darkcoin anywhere in that wallet. And any retailers who accept DRK would also automatically accept iCoin and vice versa.
(*) I just picked the name iCoin as an example because I always loved that name and branding, too bad that coin's been dead for a while now, I'm sure its brand could be acquired easily if so desired.
