I have seen many projects that use the swap concept and ultimately end up with a loss pull, so the most important thing to do before actually investing in a swap project is to analyze the people behind the project, remember your money is very valuable, don't until you lose it because of your negligence in analyzing, stay careful because there are lots of project scammers out there
I guess that is because there are now lots of swapping platforms and needing more of it seems not necessary anymore but I think you are also referring to rug pulls when you say loss pull and this is not only limited to those said projects.
A project can have legit people but they still can fail, so it's not enough to only use it as a basis when judging them. There are also other important points to look for actually when deciding if what to invest, one example is by looking at their road maps and whitepapers, although the people / team members are also included in either one of them because they are packed with lots of information.
