It resets after 3 days so you can only download roughly 40GB every 3 days. You can see in your my account page on their website how much you have left.
Unrelated to filejoker, but uptobox(if not blocked in your country) and 1fichier are very good free alternatives. Even without an account, you can get fast downloads(I sometimes max out my connection speed at 2.6MB/s and consistently get over 1MB/s) without having to enter a captcha which is great if you're using a download manager(I downloaded for over 100GB in less than a day using those 2 in combination, but mostly uptobox).
Also, most poster will use the same files with their different hosts so you can download a different file from every one of their host and you'll get the same result as if you had only used one host.
