Card cashback thresholds after BNB meltdown

Binance lowered the bnb holding requirements some time ago after steep appreciation of the coin.

The sweet spot in my opinion lies at 100 bnb, providing 5% back in bnb on Visa purcases. The old requirement used to be 500 bnb.

Do you think there’s a risk that Binance raises the thresholds again if bnb continues to sink?

Or can I secure a 5% cashback till eternity by buying bnb with €20k or even less if the market falls some more?

I only have about a dozen bnb at present and haven’t bothered to get a visa since the cashback at that level is so low.
