It all depends on how risk averse you are really. The fact that you've come here suggests that you're fairly comfortable with high risk, given the volatility of crypto, but there's a significant difference between Bitcoin on alts. I'd always suggest you start with Bitcoin and have a majority holding that - don't rush into any alt project, but there are a lot of them that are useless. Know that in Bitcoin you've got the most stable asset, which might not be doing x10, but has much more potential for growth than most stocks and other investments out of the crypto space...you should be comfortable with that. Don't succumb to greed and emotion, analyse projects and make informed decisions.
I could not agree more with you,,, we all know who come to crypto that this is a very high risk vehicle and extremely volatile asset. Yet still there are some people who think they can lower their risk and put everything in baskets. Ask Galaxy Digital, the world's biggest crypto fund, how they did in 2018 (70% loss). These were experts too. And they lost money. So the lesson is, advice is advice, but make your own decisions with money you must consider gone.
