Actually, I do not fully recognize those exchanges that you mention. I do not use exchange that is not popular wherein it doesn't have strong community. The exchange that I want should have good reputation not only from customers but also in different medias in the cryptocurrency market. I will never use a exchange that I do not fully recognize because for sure that there is something fishy or something bad that may happen. I will learn to the mistakes of the other which is to use good exchange and avoid opening in an exchange that is not popular and have poor reputation.
agree, i also never used such exchange. better to avoid some shady exchange with fake volume. there's a lot of better exchange that already trustworthy proven by the community and also have good security
