Monero (XMR) was not designed for the dark web but to solve specific issues that Bitcoin was unable to perform. Privacy, speed and safety were the issues the coin wanted to address. With these features, users had trust in the platform and were ideal for both legal and illegal transactions. However, the shift from Monero to other platforms might not solve the issues of privacy; the migration could have transaction cost implications.
There is a lot than Monero should do if they want to increase their coin price and restore investor confidence in the market. Regulation compliance and a bit of marketing can do them better at the moment. Clearing their position would also give them a boost in terms of investor confidence and partnerships.
With Litecoin reluctance to achieve full privacy, Monero (XMR) can still redeem itself by putting their house in order. If it is true that the platform is compromised and nothing done about it, the price of XMR might plummet further causing panic to the community and the Dark web operatives. For now, it is a wait-and-see satiation.
