Why would you really want Eth or altcoins?
Every altcoin season, sure there's a handful of coins that skyrocket 10,000% over a week. If you get those right, if you really see DOGE or SHIB or whatever coming and you time the meme right, you're set. But that's true of any market, like the stock market. Chances are, you won't get the to-the-moon shitcoin pick right, you won't wager enough for it to make a difference, or you'll sell at the wrong time, and these things always crater.
It's all garbage, or you can buy bitcoin. And if you don't like that then you should stick to traditional assets, stocks(index funds primarily), real estate, cash flowing businesses, commodities, upskilling yourself/education...etc.
