The Loopring project has no risk and security problems. Used initially for ERC20 tokens and finally all blockchains. In this way, money exchanges and similar transactions can be handled easily from Loopring without the need for other sites. So I can say that it is a very simple and useful project.
Support department takes care of everything. I can say that it worked for me so much.
As far as I understand, the project is supported not only manually by humans but also by robots (artificial intelligence).
Finally, I can recommend it to everyone saying that it is a very useful project.
