That is a fact, there is also no proof to the contrary though. That is why I said -think-. Just based on perception of a pegged currency, but I accept that is only my opinion, other may or may not share that.
From a profit point of view as Shareholder, I feel that we are paying twice while the high spreads would almost pay back for themselves. Why not make the spread even higher, so trader can get their rewards without subsidy from Nu? We started with a perfect peg minus fees, we now have spreads of over 1% on either side minus fees and I believe we are still paying too much in proportion.
