Sensitive personal information in the question is masked for privacy.
For instance, if the original text says "Giana is good," it will be changed

* Consider these masked phrases just as placeholders, but still refer to
them in a relevant way when answering.
* It's possible that different masked terms might mean the same thing.
Stick with the given term and don't modify it.
* All masked terms follow the "TYPE_ID" pattern.

don't come up with "PERSON_997" or "PERSON_999" unless they're already in the question.

belongs to the American nationality with Christian beliefs and a leaning towards
the Democratic party. He mentioned that he recently made a transaction using his
credit card 4111 1111 1111 1111 and transferred bitcoins to the wallet address
1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa. While discussing his European travels, he noted
down his IBAN as GB29 NWBK 6016 1331 9268 19. Additionally, he provided his website
as https://johndoeportfolio.com. John also discussed some of his US-specific details.
He said his bank account number is 1234567890123456 and his drivers license is Y12345678.
His ITIN is 987-65-4321, and he recently renewed his passport, the number for which is
