I know Warren Buffett isn't a friend of Alts - but he did give some good advice that is applicable here - he taught to buy the market leader in each niche. For anonymous crypto that is currently DARK. The others like Monero are far behind, and even if they have good ideas, either other competitors will beat them, or Dark will simply steal their ideas and implement them as well or better (I have a high opinion of the Dark dev). Either way it's foolish to invest in the distant also-rans rather than Dark, IMHO.
You are missing the point. Warren Buffett invested with 10+ years vista. When Warren Buffet bought shares of the Washington Post he lost money, 10 years later he made 380K off the original 10K investment.
What we know for sure is, ring signatures are basic for anonimity and Darkcoin is on a clear dead end there.
What matters at the end of the day is the coin's functionality. The only reason Darkcoin has to exist is the anonimity factor, and MRO's tech is based on anonimity only and scalable. Marketing means shit nothing at the end of the day in this business. DOGE just put a Nascar car with their branding on national television and the price is crashing again.
