So you have $10 of bitcoin in your wallet, yes? Or are you still trying to redeem it? bitcoin.com recommends several different wallet services depending on your specific needs, so we can help you better if you tell us what you have.
If you're interested in buying more, I've found that the easiest way to do so with a bank account is through Coinbase.com. They also offer other blockchain currencies like Litecoin and Ethereum. I've heard that their verification process is a little difficult, and that some users have had other difficulties, but I'm unaware of any other direct purchase service like them.
Don't be afraid to ask whatever questions you might have, we're happy to help.
