I received huge amount of money in my Maya from BPI

Hi everyone, this morning I received 40,000 pesos out of nowhere. I was asking my contacts if any of them accidentally sent me money, pero none of them did.

Until now no one is contacting me about it. I am willing to give it back naman, kaso I don’t have any info on the sender.

Question — can I put this 40K in the meantime to my Maya Savings? I currently have 12% p.a. and I’m thinking sayang yung 40K if it just sits in my wallet.
