If what you mean by shady character is a coin that is not clear like a meme coin that is trending, then what you should do is get out of trading in coins like that, not get out of trading.
New coins whose development is not clear will make your trading focus only on luck, if you are lucky you can make big profits, if not you will suffer big losses which will make you frustrated, but if you are an experienced trader then it is difficult to be interested in coins like that because experience has taught you many things because what is happening now has also happened a long time ago, where many new coins have emerged which more often give big losses to real traders unless you are involved in a group that is used to dumping and pumping, which make you only trades relies on the movement of the group.
I do agree that people should try to avoid anything that looks even remotely shady. We have tens of thousands of coins and tokens in this market, there is no reason to risk anything, if nothing else seems ok, just put 100% of your money into bitcoin until you find something you like. After thousands of tokens and coins, you will find one that makes you feel like it is not even a single bit shady, and you would love to invest into it, there will be zero doubt about it and you will be happy.
You can still be wrong about it, which is fine, but I think that means a lot more than what people think. This is why I think it should be something that will make it better, and we need to just adjust to it, so do not rush into any investments.
One of the main reasons on why people would really be trying out to dive and get involved with meme coins is that they could make huge money or even getting rich on the moment that they would be able to hit up the right spot but as said that with thousands that been launching then it would really be that so hard to spot out on which is one. This is why i do consider out that trading or investing with meme coins would be somewhat be considered to be having some part on gambling approach because it would really be hard to apply any analysis into it on which we know that this isnt something that would be possible into these earliest
time on these tokens are really that into on which this isnt really just related to meme coins but even into those projects.
There's no way that you could really be able to ensure yourself that you could really be that successful on any trades on which is why it would really be that better that you should really
making yourself knows on how to handle up such risks on this regard.
