I am not sure when you changed it but I realized that there is a noticable spread even in BTC that has big order lists. I checked the price live in Binance (that is a connected in smart engine) and on swissborg app live rate. It has a nice spread on both buy and sell options.
Even if it is a small one, it is not following your transparency ideology. So, please fix it or some of the investors will loose the trust.
