They are mined in similar ways. Pirate Chain or ARRR, is worth exploring to see if it passed muster, i am not advocating for anything in particular, but i have friends in oppressive countries and i want to find safe ways of transferring "money" to them that are not only anonymised, but also don't draw attention. The pinch point is always the conversion from crypto into fiat cash, and the underlying threat to Tether, being potentially backed by a collapsing Chinese housing market is a real and present danger to al crypto. The benefit of Pirate Chain is that its low value, lower than monero.
