It's hard to say. You must be careful when you are interesting to trade at the early of pump. When you are trading at the early phase after listing and you must take care with the liquidity of tokens. I meant when you are swapping it to another and it will be a very big risk for you.
Sometime you will be swapping your money for a small amounts of tokens if you are doing it when the liquidity was very small.
You can buy that after listing but you can also try to make sure if the liquidity already added
Really hard to tell because of some scenarios.
-You buy on dex or cex knowing that it would be listed on top tier exchange -- neither the price would pump or dump after listing.
-You wont like to miss out the possible rally whenever it would be listed but totally buying on pump is suicide.
-Determining on whats the bottom or peak price is always been not easy to be done.
So take your risk and be aware of that whenever you do deal with low caps or something in related.
