The pools even have a statistics page, and you can set up notification to let you know if your miner stops mining for some reason. Wallets and Exchanges In every Altcoin mining program, there is a place where you need to enter your mining pool address to mine to. This is not hard.
Altcoin Trading for Bitcoin
Start by setting up an account at an exchange that only deals in cryptocurrencies. After you open up your account, go to the Balances, then Deposits and Withdrawals section. Enter that address as your mining pool address in the Claymore program. The specific place to enter the address is in the config. Zcash uses a single address for mining, the t address. Poloniex provides both for you. As you keep running your miner, the amount of Ethereum, Zcash, or Monero you own will grow.
I have other articles that recommend what to do with it, and how to keep it safe. After you get a little bit in your account, take a look at my recommendations on security.
If you decide this mining is something you want to continue doing, a PC with a graphics card is not the most optimized system available. You are going to want to have dedicated hardware and be able to run the system remotely, with no monitor, keyboard or mouse. Mining with Bigger Gear If you have a little bit of basic technical know-how, you can go one step better than mining with a gaming PC. You can build a relatively inexpensive mining rig that is maximized for GPU utilization and cooling.
These rigs can run either Windows or Linux. If you are going to have 3 or less, Windows is ok. More than that you really want to think about using Linux.
