This is why i disdain diversification in favor of big bets on better known, smaller cap coins. ETH/BTC have all of the downside of some black swan event but way less of the upside
im split between cardano and xlm and intend to ride those motherfuckers until im well, well into 7 figures inshallah.
I don't think either is a "long-term hold" as in you can safely leave your retirement money in those coins. They seem relatively stable as far as cryptos go though
