Have been following this thread for months now and what I saw is just another one posting His shitcoin or those who does not truly understand the market and just telling what they think will climb tomorrow .
for Bitcoin it is clear that there is no doubt because it is indeed very feasible for long-term investment,
to diversify I think that's a good strategy.
No doubt about the bitcoin but the OP was asking what altcoin is worth it, I'd say that only selected altcoins are really worth it to buy and hodl while the market is dipping, but shitcoins/memecoins? I doubt people can still get lucky about it because these whales are moving in an unexpected manner so there's more chance that you'll get losses than gains, moreover, it's not worth it in the first place because these coins doesn't have any utility.
You can take your chance but be ready with the risk that you'll going to take. There are many investors / traders who are playing with such kind of investment and most of them are losing money. It's the timing and luck that will allow you to earn from shit/meme project, same deal with gambling you will wait if you will win or lose at the end.
Better to invest with solid assets which have established usages and communities, once Bitcoin experienced huge pump expect those coins to experienced the same not totally all but most of them will.
on the other hand making decisions by taking risks is also good but still it needs to be considered first,
investing in solid assets like top coins is a great choice.
