hi..I'm using the adsense account from the last 2 month and when yesterday checked my account it's showing 50$ can anyone tell me the right way to retrieve the whole of the money?
You need to wait until it reaches $100 and then they will automatically pay you at the next payment cycle.
the PIN from adsense should have been sent to you once you have 10U$ in your account, after that wait for your money to reach 100U$, also check your account if it's on Hold or not.
You need to wait until you reach $100. Read this for payment details. google.com/adsense/support/bin/static.py?page=payments.html
all you can do is wait to meet the 100 dollar threshold - then you get paid in the next months payment cycle.
