However, trading Bitcoin successfully is not a matter of luck or guesswork. Profitable traders spend a substantial amount of time learning how to trade and how to overcome the many risks involved with trading.

By mining, you can earn cryptocurrency without having to put down money for it. That said, you certainly don't have to be a miner to own crypto.  You can also buy crypto using fiat currency (USD, EUR, JPY, etc); you can trade it on an exchange like Bitstamp using other crypto (example: Using Ethereum or NEO to buy Bitcoin); you even can earn it by playing video games or by publishing blogposts on platforms that pay its users in crypto. An example of the latter is Steemit, which is kind of like Medium except that users can reward bloggers by paying them in a proprietary cryptocurrency called Steem.  Steem can then be traded elsewhere for Bitcoin. 
Once you have a Bitcoin wallet, you use a traditional payment method such as credit card, bank transfer (ACH), or debit card to buy Bitcoins on a Bitcoin exchange (example: Coinbase). The Bitcoins are then transferred to your wallet. The availability of the above payment methods is subject to the area of jurisdiction and exchange chosen. Here is a screenshot of the Bitcoin interface showing how to buy and sell not just Bitcoin but also Bitcoin Cash, Ethereum and Litecoin​, which are other popular virtual currencies. As you see, it's as straightforward as clicking on the "Buy" tab if you want to buy, and "Sell" tab if you want to sell. You select which currency you are buying/selling and which payment method (your bank account or credit card) you want to use.
