So my question is: is this market still profitable for new projects?
You said in your previous post that you are talking about "new projects", so your subject title, and kind of confusing TBH.
Anyway, there are new projects that are being created daily, but not all of them will survive. There are lots of projects right now that has been listed in Coingecko, and Coinmarketcap, but most of them are either no liquidity at all on exchanges, no community behind it whatsoever. Most of the new projects are ending up as a scam, or an abandoned one especially if there isn't that much support from their investors.
Is it still profitable? Yes, but the chances are very low. What I mean is that you need to prepare for the worst if you are investing into new projects because they have a high chance of it being a rug pull. Yes it's still profitable, but the chances of you as an investor to get profit from them is very low. This is also the reason why I don't invest into new projects. If I'm lucky, I might make my money x10 or even x100, but what are the chances of my money going to 0? High, so the risk is high though the reward is also high, but it isn't worth it for me to try.
