Everything the OP mentioned is completely foreign, none of which I'm familiar with, Raydium? Dexlab? saber?,
I don't know if this project is still active? why not choose a good project and have good fundamentals?,
in the Solana ecosystem there are several projects such as Terra, Link. GRT, GMT and AUDIO,
these projects have good fundamentals in the solana ecosystem, investing there will keep you safe
That's the thing about crypto, I do know raydium and I do not know the others. But in crypto, the ecosystem is so vast that sometimes we can't know all of them. If you are a person who is very interested in SOL and have a big SOL investment, then you will spend your times trying to learn more about it and this will result with you getting to know more and more SOL projects as well.
Because, you have a lot of money in SOL and you want to know what's going on in that ecosystem to see how your investment will do. This is why it is not really that much of a big deal, it's understandable that you may not know these, I do not know many neither, it is just not something we give attention to and it is big deal for them.
