Hi Md Nahid,
There isn't any specific number of hours required for you to keep your Upwork account. Please keep in mind that you stay in line with Upwork TOS to keep your account active.
We may suspend accounts that violate our Terms of Service. You can read about our most important policies to learn which account activities and behaviors are off-limits.
Depending on the severity of the violation and its impact on the Upwork community and platform integrity, we may suspend your account by either restricting it with a temporary hold or permanently blocking you from using Upwork. Accounts may be suspended due to a single violation or repeated violations. You can learn more about Trust & Safety actions here.
