Here is a view: Its a lot of work for an uncertain payoff, why not just own, say, 75% BTC 25% ETH and call it a day? ETH has even been beating Bitcoin in last 15 months or so, I think thats what a core crypto portfolio should look like. So, now, an alt portfolio has to beat ETH as well (in my mind).
Maybe it can be done, maybe it cant. But if crypto is the future, that core portfolio (properly hodled) is likely to beat 99% of everything else out there. Why research for hours on end, having to dodge all the crap out there (all the stuff that youtubers love to pump), have a lot more volatility in the portfolio to at the end of the day, probably produce a worse risk adjusted return?
Valid perspective and most likely more sensible.
Yet your comparison of ETH to BTC is also true of ALT to ETH. As for risk-adjusted, the rewards are commensurate with the risk.
Although I see BTC and crypto as a whole much higher than it is today, the market has to digest this new achievement and reality from a psychological view.
