Normally I use Bitcoin to buy things from online. When I buy a product from a local seller, I offer him to accept payment in Bitcoin. Because most of my money is invested in Bitcoin. Sometimes they agree and sometimes they disagreed to accept it because of its volatility. I also use Bitcoin to buy online gift cards, virtual Visa cards, and MasterCards for boosting my business page.
I consider at this moment to choose bitcoin as payment but when there's a dump of bitcoin price, I will not use my bitcoin instead, just hold this and become my asset. I don't regularly use my bitcoin purchasing online if does not important to me, I will not use my bitcoin because I threaten my bitcoin as a valuable asset that someday there will still have a profit.
Use your bitcoin if that is very important, but if not, I rather choose fiat upon having a payment option than choosing my precious bitcoin.
