Question #1 Can I get dollars, real money, or cash for Bitcoin ANYTIME?
If so, HOW?
If you purchase Bitcoin you will pay real money for it. If you sell your Bitcoin, you will get real money or dollars or USD for it. Bitcoin isn't a secret if you are buying from an exchange. Both of these companies will KYC you. KYC= Know Your Customer = giving them your info just like you'd give a bank. They HAVE to ask you for your info it's the law. Both companies below are based in the US. Both make it so you can buy Bitcoin whenever you'd like and sell it whenever you'd like. The value of Bitcoin does fluctuate so if you are buying because you hope to make a few bucks? I understand your line of thinking.
Keep in mind that fluctuations can happen anytime and there's no guarantee you'll sell it for more. If you need to get your money out and can't wait, you may lose dollars but you won't lose Bitcoin. Wait it out and/or read more about risk below.

The 2nd Most Asked Question
What is my risk?
Everything is a risk. You don't take risks you can't afford to make, correct? I feel safe in Bitcoin, that's just ME. It is not financial advice. Others feel safe in Apple, stuffing their money in a mattress or savings account at your bank. These are all risks. When you take a risk, it's a good idea to try to minimize your risk as much as possible and if you want to get into it? Keep reading and learning so you understand what you are buying. Also know companies can go out of business or get hacked. It can happen anywhere.
If you want Bitcoin to hang onto long term? You move it. There are ways to take it offline and keep it safe. I don't want you to get confused, so let's leave it there for now.
If you want to buy Bitcoin? Buy what you can afford to lose and put it away long term. Don't watch the day to day. At this time, Bitcoin is the best performing asset of all time. It's a risk just like anything else.
Use the best resources, learn what you can and decide if the risks are worth the potential.
