I won't go into details about how to sign up and make an account because that should be pretty obvious. Also Bittrex now requires you to add your Identification (KYC) in order to trade.
Security in crypto is very important though, so first thing you want to do after you sign up is head over to settings (1) and click Two-Factor Authentication (2).
You will need to download Google Authenticator from the Google Play store on to your phone. Once you download it, select the scan code option and aim it at the QR code Bittrex provided so it can be added on to your phone.
Make sure to take a screenshot of this page so that you have a record of the Secret Key (3) in case you were to lose your phone. Having a backup is important, this way you can remove 2FA as a backup to get to your account if that was to happen without having to file a support ticket and wait 24-48 hours.
Now look at Google Authenticator and it should give you a 6 digit code associated with Bittrex, input this into step 4 and click enable 2FA before the code expires and a new one reloads. Then you should get an email, open and confirm it.
To deposit Bitcoin or any other coin on Bittrex, look up the coin in the search and then click the + (plus) sign, the window will pop up and say Generate Address, once you have that you can copy the address and send bitcoin into it.
To start trading, click on B Markets (1), you can change the number of rows of coins you want to see (2), and either select one by clicking on their ticker name (BTC, ETH, and so on) or use the search.
This just shows you the stats for the day on the coin you are trading, you can change the timeline to minutes/hours/days to get a better look at how the coin has been performing short and long term by looking at the graph. You can also scroll to zoom in/out and drag the chart to see further back
This shows you the market history for buys/sells as well as the orders you have done so you can keep track of what price you bought in at.
