A likely answer is that as historically Luna was trading at 50-100$ it had a minimum price specificity of $0.01 or something, so the exchange might have converted lower buys/sells to $0.01 when it was trading below that

They take their fees as a percentage, so yeah of course crypto.com would benefit from a higher price?

What does fees have to do with price? If I trade a $100 worth of a coin at $5 vs one at $10, the fees captured by the exchange is the same.
