I have a seed phrase, password, two sheets of addresses, and a paper wallet with a public and private key and a QR code. How do I liquidate my Bitcoin back to fiat?

Please clarify. Is Bitcoin Cash the same as regular Bitcoin? It seems to me that awhile ago Bitcoin owners were being encouraged to move their Bitcoin into Bitcoin Cash in order that they might receive twice as much return from it than if we left it in Bitcoin. Is that still the case?

Bitcoin Client Software and Version Number: DSTM, v0.6
Operating System: Win10, x64
System Hardware Specs: Nvidia Geforce 1080
Description of Problem: Miner quit functioning; now I can't get it started again. It could have a virus; I was told I couldn't use the firewall or antivirus bc it would interfere with the miner. I remember that DSTM started functioning very quickly; I didn't have to struggle with it. I might add that I have MSI Afterburner which I use with the DSTM.
Any Related Addresses: Not applicable.
Any Related Transaction IDs: Not applicable.
Screenshot of the problem: None available. I couldn't figure out how to get the screenshot into this post. It consisted of a picture of the Notepad data with my line of personal info in it. As I recall, the miner started up automatically when I had this completed correctly. I have checked with my Bittrex account; it shows some production by the miner.
Log Files from the Bitcoin Client I don't know where to find these.

A virus kicked my miner off-line and I am trying to set it up again. I get to the "edit" page, put in my data, save, but it doesn't take off, which it did when I first set it up. What am I doing wrong? May I turn on the firewall to run with it? If so, what should I put in the firewall as a exclusion?

I am following the Beginner's Guide To Zcash Mining and am at Section 3, "Download the EWBF Zcash Miner." I am using Windows 10, X64, with a Nvidea Geforce GPU 1080 8GB. Now, I have gone through the instructions multiple times, and I cannot get the "Zec Miner" to extract to "EWBF Zcash Miner" and show up on my desktop. The thing that shows up on my desktop is "Zec Miner." What am I doing wrong?

I had about 1/3 of a bitcoin in an internet (Blockchain) wallet on August 1, when BTC forked. So I tried to claim my Bitcash in an Electrum wallet using step-by-step instructions here: https://99bitcoins.com/how-to-claim-buy-bitcoin-cash-guide/. But my system varied somewhat from the instructor's system so that at the end I did not have any BTC in my Electrum wallet. Also, I went into bitinfochart.org to try to see if I had any BTC showing in Bitcash, but I could not make sense of their website. I would like to send a photo of my Electrum wallet. "cannot start QR; zbar not available" it says. And the balance shows as "Balance: 0 .mBTC".

I would like to know if Bitcash has any BTC that they are holding for me, and if so how to claim it.
