Doing my final presentation on bitcoin. Any tips?

I am required to put together a 20 minute presentation for my technology and society final on a technology that has or will have a large impact on society. I figured bitcoin would be perfect, but I am far from an expert and pretty new to the space. The rough outline of my presentation is below. Is anyone willing to give advice on important point that I should add? Or any points that I might not need? Keep in mind that this presentation is to a class that has no knowledge on Bitcoin.

1) What is money? Go over the 5 properties of money (Durability, Recognizability, Scarcity, Portability and Divisibility) and talk about previous forms of money and why they have failed

2) Talk about gold as a currency, the Fed printing money and why other countries dollars have and will continue to collapse (prompting everyone to question why we have a middle man in the first place)

3) Introduce the idea of bitcoin and give a dumbed down explanation of transaction hashes and how blocks are verified on the blockchain. Hopefully explaining how btc is completely decentralized. Then move on to explain the hard cap of supply and other technical components like the long transaction times for security, SHA256 and that 100% of btc is intrinsic value (ideal for a currency) Whereas gold carries some industrial value.

4) Now that the idea of this perfect currency is out there explain why nothing will overtake btc because money is a winner takes all kind of deal due to liquidity.

5) Introduce the lighting network and how it can help reduce fees and speed up transactions making everyday use easier.

6) Answer any common FUD related to price volatility, energy use, no backing value, the parabolic price increase that we have seen so far, governments and countries bans and regulations. ect.

I just wrote this up really quickly and think I definitely missed some points so please be brutally honest and critical. Any advice you can provide is greatly appreciated!
