In general, the risks are mostly for people who do not want to study this area thoroughly. In order to avoid this, I advise you to add to your knowledge bank some facts that I have learned from https://coincodecap.com/how-and-why-to-wrap-and-unwrap-ethereum. If you want to avoid mistakes when choosing an exchange, it is important to pay attention to several things. I always check the reputation of the platform - if it has a lot of negative reviews, it is better to look for another. It is also important to look at the commissions, so that they do not eat up all the benefits. And I never keep more on the exchange than I intend to exchange - that way I can minimize the risks of losing money.
