My BTC exchange them for other currencies, if I want money fiat I send them to a page where I can change them, for example, in the Tradesatoshi exchange that is the most I use, I exchange them for DOGES and send them for a website and change them for me local currency, but I send them to localbitcoin that I can also change them to fiat money, but in my opinion to trade with it and look for profits is better than spending them on goods and services.
