The DarkNetMarkets has been an absolute success, especially where LSD is concerned, LSD was on the brink of extinction and the DarkNetMarkets along with the amazing vendors willing to sell it have saved it.
Everyone will have there own opinion, but personly I'd like Monero to replace Bitcoin in 2017.
Happy New Year
Bitcoin isn't going anywhere. Monero will never become anything more than a niche alt coin. Happy new year :*
