Hello sir. What is your alternative to convert BTC to monopoly money in an hour on sunday? Or you just avoid that and spend only BTC?
Why don't you use cash? Or your credit card? Bitcoin is good if the seller accepts bitcoin. If he/she doesn't want bitcoin, you need a middle man like wirex to get shit done. And guess what... That middle man pays mastercard/visa to get your shit done and you pay him to get your shit done, means that you pay for something free.
Either find the sellers who accept bitcoin directly, or stop insisting on using bitcoin.
