Is this a scam

So again, my husband is involved with an Asian woman online that has convinced him that she has an "in" to short term trading. She has romanced him, stepped into my married via him opening this door to making money. Here's my question, he has a bitcoin number and an onchain account. He texts this woman every day and stays connected because he says easy only money. He claims he doesn't care if it's a scam or not because he's making money by her informing him as to when to trade a node and get in and out. She walks him through it. He claims his last transaction made $400. If he has his own accounts how can she scam him?
