Exchange rate WXT wrong

Hi, I realized that I cannot use actually WXT as coin for payments. strange… as it is the native token. Don’t get it. Anyway, i am trying to exchange it to EUR and the thing is that the exchange rate which is displayed prior to doing the swap is about 2,5-3% below market price - PLUS fee for the swap.
Why? Please help. Thanks in advance!

ma sopratutto: perchè ora il minino da poter scambiare è 28000 WXT??? oggi è 150USD 130EUR??? prima era 50USD 43 EUR

but above all: because now the minimum to be exchanged is 28000 WXT??? is 150 USD!! before is 50 USD 43EUR!!!
