If you're looking into buying a mining contract, use a calculator like CoinWarz. Then you can see an estimation of what you'll make and whether or not it's worth the cost.

Miners and mining contracts are for those that want to support the network and secure the blockchain while also getting some token returns. They aren't an investment that pays off in terms making more BTC but you eventually break even and then some in terms of usd down the line because of the deflationary nature of the currency.

Virwox.com accepts PayPal and credit card.

You have to buy SLL than exchange it for BTC, but you end up paying about a 30% premium once you add up all the transaction fees.
