I was also amazed and I wonder why does it say that after 180 days you could withdraw funds to a bank account in US?

This is a condition established in their policies.

Once my account was locked they established that waiting period, supposedly to resolve any legal dispute.
Currently, those 180 have passed. They notified me via email that I can already withdraw my funds, but the only way to do it (due to policies) is to make a transfer to a US bank account in my name.
