Nicehash Pool Stratum?

So I am selling my hashing power to Zcash for bitcoins rather then Zec and converting them to BTC later. I followed their tutorial but it just says enter your bitcoin address which makes sense but for the server it just says enter usa. Is it already in the .exe file to know what stratum server to point to by typing usa or am I mining I to nothing? I check on the zcash website and my wallet didn’t show up. It might take longer but I had been mining for around 10 hours straight. All the help would be appreciated!

Go to and enter your BTC address to see your balance.

Yeah I figured it out
