Before getting started with Bitcoin, there are few things you actually need to understand. First you need to know that the Bitcoin ecosystem allows you to exchange and transact money in so many different ways than you normally do. so before using Bitcoin for any serious transaction, you should be well knowledgeable about how the Bitcoin system works and be fully aware of the problems associated with the fiat system.
Also note the following
1. Note that Bitcoin transaction are irreversible. Therefore one need to be extra careful while doing transaction.
2. The price of Bitcoin is still volatile i.e it does not have a fix price for it market price.

All of your points is pretty common and lots of people already know about this information. So what I can suggest to you is to research further more information so that you can contribute new information to people.
I'm sure you can do more better than sharing generic this information. But I still admire your effort made since there maybe few people could find your post helpful to them.
Bitcoin is risky so people should try to gain information then understand every important detail that need to look for so people could avoid any potential issues that can hurt them so bad.
