There are two main methods of obtaining Bitcoin - one method is like buying any product, you go to where it is being sold. The grocery store for Bitcoin in America and for much of the world is the website Coinbase. On this page, you will be provided the "correct" link to use to visit Coinbase - that will earn you 10.00 USD worth of FREE Bitcoin.
The other method for obtaining Bitcoin is by "mining" Bitcoin via a "Bitcoin Mining" piece of equipment - a modified computer designed for mining Bitcoin and other "Crypto-Currencies". All types of mining equipment exist from inexpensive to very expensive - operating these machines can be "testy" and the information curve to get started is quite steep. The machines are also noisy and generate a lot of heat while consuming tons of electricity.
Because of the above negative attributes associated with "mining Bitcoin" - most people who "mine" do so by buying into "mining farms" set up around the world in low electricity locations. One buys into these "mining farms" via purchasing a "contract" from one of these mining firms. Some mining farms claim to have over 500,000 people who own mining contracts - this website will also provide the "right" way to sign up for one of these mining farms.
