Yeah it's a tragedy but the lesson is beyond learned as you can imagine.
The bulk of my crypto portfolio is in BTC and ETH, but I like to keep at least one full coin in anything with at least a $1 billion market cap so I also hold litecoin, filecoin, chainlink, stellar lumens, unisap, aave, Ox and algorand. There's probably more with 1B market cap but I trade on coinbase and those are the ones they support. At the end of the day, I believe in BTC and ETH will carry the most value in the long run but I've had a lot of gains from alts so I suppose they're worth it for now. I also think my $1 billion rule is a pretty solid strategy because the trashier coins tend to be a lot more volatile and I don't have time to actively monitor them like I do with stocks. Plus crypto markets never stop trading so it takes a pretty sophisticated set of automated triggers to keep a balanced risk strategy going with the lower alts and ain't nobody have time for that.
I also recommend USDC since it's pegged to the US dollar, it's not a great investment since it has a tiny APR but it's a good way to keep a semi-liquid emergency fund going. It's also where I stash a portion of my realized gains from crypto and set aside the tax portion of my capital gains from stocks throughout the year so I don't have to worry about paying up when it's time to file every year.
