Sorry oversaw your answer. I did not question moneros usage in darknet markets, use whatever you want. but if you already hold bitcoin which is a way bigger amount of people you can go lightning->ecash if you need full privacy for specific txs. you can also use lightning with private channels for day to day usage. monero plays a niche role which is ok. but its not easy to on and off ramp from fiat to gain that privacy and because of that more and more people getting onboarded via bitcoin and can get access to privacy txs via ln (+ecash). In the long run this makes monero obsolete imho. will it be a niche? possibly yes. but not for mass privacy adoption.
