cryptobull is one of those crypto exchanges that failed to meet users expectations coupled with lots of flaws such as little information,has little or no recognition from traders.
According to my research i noticed that access to the main page has been restricted from users as it is practically impossible to have an access into i far it's developers haven't done enough in supporting the site so it can gain the trust of potential users, this has led to just a very few number of users making use of the platform
I will like to advise anyone planning to use this platform not to take the risk, it is not worth it as users risk losing all of their investment at a go. The developer needs to update on what is going on if it's going to recover or not but as of this moment funds placed are at risk therefore investment shouldn't be
