Hello,
Normally this is not possible.
However, it is probably the case that the deposit happened with a version of the wallet prior to 3.6.5. In 3.6.5 a fix was added to count deposit fees, that were previously introduced in the CoinPayments adapter. In other words, this must be related to: https://www.dashed-slug.net/forums/topic/negative-balance-request-for-a-pending-balance-feature/#post-4285
If your users use the latest version of both the parent plugin and the coin adapter extension, they can be assured that this will not happen again.
kind regards
