Many of the 'long tail' of cryptocurrencies are currently only available at a handful of exchanges, many of which will not accept direct US Dollar, GBP or EUR deposits. In order to make a trade, you need to:
Create a Bitcoin, Litecoin or Ethereum wallet
Create a Steem Dollars wallet to recieve your coins
Buy either BTC, ETH or LTC at an exchange you trust, making a deposit by bank transfer or credit card
Transfer the major coin you have bought to an exchange that trades SBD
Exchange your BTC, ETH or LTC for an amount of SBD, depending on the current exchange rate
Move your Steem Dollars coins from the exchange to your private wallet to protect yourself from hacks or bankcrupcy at the exchange
