A while ago Louie Helm recommended buying Darkcoins. After he did the price of a darkcoin went up to more than 10$, but now it's down to 2$. Is it still a good idea to buy darkcoins, that is, is their price likely to go back up?
Honestly I doubt cryptocurrencies are any better than a random walk (unless you have some special foreknowledge of some extra attention the currency is about to get.)
