Overkill.
No. It's overkill if you don't refine your questions. If you ask too vaguely, you'll get much more info than you may need.
Do you know how banks send the money internally, how they store them, how your VISA card communicates with the bank when inserted into a PoS? I guess not. Then why you try to focus on all the details for Bitcoin?
You need to understand a small number of things:
1. Wallet safety and computer safety.
2. How to look onto a website to check if the fee you choose is right.
3. Install and run a simple wallet, like Electrum, how to send and receive.
4. [Maybe] How to check on a 3rd party website if a transaction was sent and confirmed.
This means that you need some 15 minutes to pay attention.
Before use the bitcoin lean the information and process. Then easy to use. If don't know any information. It nof easy to use. It digital currency. So it safely use the bitcoin. It good future saving. So don't want the coin. So lean the information of the coin. If need for more information check the market place and coin disk. Then get more information day by day. So time is important of all process. So time to buy and sell it.
