The Bitcoin price can vary throughout the world so perform your own due diligence to make sure you are getting a fair deal. The first step however is to choose a wallet where you will keep your bitcoin before selecting an exchange.
Once you have secured your wallet, the next step is to decide upon an exchange. Exchanges provide highly varying degrees of safety, security, privacy, and control over your funds and information. However, there is no excuse for not controlling your own private keys.
We therefore strongly recommend you do not keep most of your bitcoins in their service but rather transfer your funds to your private wallet.
Later, as you begin to accumulate more Bitcoins, we will share added security features such as the Ledger Hardwire Wallet to secure your Bitcoins even further.
