So to clarify. I already have an account on Coinbase. I buy a BTC on Coinbase and use that address to transfer that BTC to Bittrex. I then buy other altcurrencies there, right?

LeGaulois, thank you for your response. Two questions:

1) So I cannot just deposit money into my Bittrex account and buy an altcoin?

2) Where do I buy bitcoin or another altcoin then then? I have to buy it with actual money somewhere, right?

Thanks.

Thanks for the responses.

I am going through the video. The first question I have is, on Bittrex, the only way to buy another altcurrency is buying bitcoin first, depositing it on Bittrex and then buying some other coin with deposited bitcoins. Is my understanding correct?

I signed up for Bittrex. I would like to buy a coin on it other than BTC, ETH or Ripple. However, I could not find a step-by-step guide as to how to go about doing it? Any help would be appreciated.
