Binance is doing leverage ? Or speculators leveraged the bounce on Binance (still not really delisted until the 20 Feb). These people (if they can be reached) should more be advised to trade in spot, on places where they can actually withdraw funds to use them.
there is nothing that requires a perpetuals market to have a lower volume than the whole spot market for the underlying asset. perpetuals are derivative assets, the reason they exist is to enable trading regardless of access to the underlying asset’s supply.
side note: Binance will shut down their XMRUSD perpetuals with the delisting, but they will keep running their XMRUSDT perpetuals (USDⓈ-M XMRUSDT):
