Many tokens are listed in both dex and other normal exchanges(CEX) and many tokens have a huge price gape, i wanted to ask could i bought tokens on dex and sell on normal exchange for a quick profit it is the same token on both exchanges or anything else i need to know about?
Yes, of course, you can. It is only necessary to make sure that this is the same token (for example, at the address of the contract, the developer's site). Because if the price difference is very different, there is a possibility that these are different tokens (with the same or similar tickers).
