I think I just signed up for Bitcoin correctly.
I'm trying to receive payments from an online casino that pays in Bitcoin. What do I need to do and what kind of wallet do I need to open, so I can receive my payment?
To receive payment in Bitcoin what you need is a Bitcoin wallet.
There are several types of wallet available. Wallets are available as desktop software (full node and, SPV wallets) and, as a web service from certain sites.
For desktop wallets you can make your own choice, the official download of the software is on bitcoin.org. I have liked Bitcoin Core (which is a full node and requires to synchronize with the Bitcoin network before it will show all transactions) and Electrum (an SPV client wallet that is setup in seconds but, is not a full node).
Personally, I would always avoid web wallets since you must trust their security and it is a big, attractive target. Online services have been hacked in the past and much Bitcoin stolen.
A Bitcoin wallet on your computer is as secure as your computer, be sure to also keep a secure, private and, up to date backup of your Bitcoin wallet or passphrase. If you lose your wallet all of your BTC are gone and cannot be recovered. When using a web wallet it is not only the security of your computer at question, it is also theirs.
Also, is Bitcoin used like a bank where I can spend money out of it?
A Bitcoin wallet allows you to spend Bitcoin. It is more like a wallet than a bank. Online web wallet services are a bit more like a bank since you are trusting a third-party to hold your Bitcoin.
Note: If you are downloading software from other than bitcoin.org it might not be Bitcoin software or, it may be modified so that it is not trustworthy.
