Part 4/6:
To purchase Bitcoin, you can use a currency exchange. Since services like PayPal do not facilitate Bitcoin transactions, an intermediary like Dwolla is often necessary.
Create an account at dwolla.com.
Link your bank account and verify the information.
Visit Mt. Gox, one of the well-known Bitcoin exchanges.
Sign up, add funds using your Dwolla account, and then trade to buy Bitcoin.

In addition to buying or earning Bitcoin, users can also engage in Bitcoin mining – the process of generating new blocks for recording transactions on the blockchain. This requires substantial computational power, typically best achieved using modern graphics processing units (GPUs).
