OP's story is indeed quite strange, How a monk who usually stays away from worldly life can have a Bitcoin wallet, Op should have an understanding of the development of the digital world. Maybe the OP falls into the modern Monk category.
Sometimes in life things happen that are out of the ordinary, and someone who does things differently is a special person.
Anything can happen and their is nothing bad for a monk yo make use of bitcoin. If monk can spend fiat then a monk can also spend bitcoin , I think bitcoin is just a new money for everyone. The story of Op maybe true , it is not something I will find it difficult to believe.
