go to the p2pb2b exchange and find the history transaction where you bought that token. I'm sure there will be a record of your history inside your account. this won't include hash/tx ID but just a record like the time, amount and number of tokens.

Did you read the thread, he got the information transaction on history like date and everything but he wants something like TX Hash for solid proof. Centralized exchange doesn't have any hash link TX dude.

Ok thank you all.
How can i prove that i bought coins before a specific date?

I believe you can ask the exchange to create some letter for you about the transaction, or you just screen capture video of the history buying token and refresh it a few times to make sure is legit.
