Answer the question: why not stolen?
The answer is quite logical - the scammer is pursuing profits, and also so that no one knows that the user has just contacted the scammer. Therefore, when a fraudster gains access to a SEED phrase, it is important for him to have something to steal. Due to lack of funds, or, in our case, if there is a very modest amount, there is no reason to steal funds. The fraudster will monitor the receipts on the wallet until the amount is sufficient for the theft.
