The fastest and safest way to start owning bitcoin is to buy a mining contract from Genesis mining. https://www.genesis-mining.com/ You will receive a small amount bitcoins daily into your account.
Right now you can purchase 1 Tera Hash of mining power for $150 USD and you can charge it against your credit card. This will give you 0.00032 Btc a day which is about 38 cents USD. At this rate it will take more than a year to recoup your investment.
However 2 things are happening. 1 The price of bitcoin is still going up and is in a very strong bull phase. This means the bitcoins that are credited to your account will appreciate in value. Secondly as the price increase mining cost decreases which means a bigger payout until the mining difficulty catches up. Thirdly transaction fees are also becoming more significant which improves the possiblity of a higher payout. All these factors means that the payback time will be shorter than you think as long as the bull phase continues. The contract is non terminating meaning that you will continue to receive some bitcoin daily forever. Considering that transaction fees will replace new coins issues, this is possible.
