a coin that hasn't listed in cex to be frank, always have that risk of lacking liquidity even for cashing out sometime its just not possible thats why investing in altcoin with low liquidity i think is always a bad idea because there's just no guarantee that there will be liquidity, also the devs could remove liquidity they provided anytime.
to be frank here, cex has standard of listing the coin they think deserving to be listed, and im talkng about good cex with reputation, if a coin doesn't make it, then I doubt its that good.
at least get listed in a cex and see how things going and then i will try to invest, otherwise if its full blown only available in dex i think i will pass.
because there are simply too many things that could be happening if we invest some big amount to it, rug pull for example, we can't really audit the smart contract by a glance can we?
Investing in such tokens is a big risk, I agree with this, but for trading they can be acceptable, besides, when a pump occurs on such alts, then during the period of such activity the volumes grow very well and there will be no problems with liquidity either. And for investing, I wouldn’t risk picking up such alts, it’s too risky for me to decide to invest my money in it.
For long-term investment, we have Bitcoin, this is an asset with which I will always feel confident, so why should I create risks for myself that could harm me.
