If we must sound professional from the way of our presentation, then we have to consider how important this is, because our way of presentation matters most in them getting being convinced, all i will be saying will be as directly base on what the bitcoin whitepaper interprets, i will also ensure i maintain being consistent and give the direct implication of bitcoin adoption, try to convey their minds away from the general misconception around the world about bitcoin.

Now, give it a thought why government never said bitcoin is a scam and why they've agitated to only adopt its legal tenders only when the decentralized blockchain is set up centralization were they could regulate it? That's to say the government already has foreseen the realistic potentials of bitcoin and then became attractive to it.
I guess they'd be bothered about the technological aspect of it but would get to let them understand the highily level of advancements we're today in the 21 century where most invents becomes possible with technologies.
Furtherly, I'd make them understand the thought of Satoshi Nakamoto inventing bitcoin was to introduce and advanced and uniqueness of financial system which can be volatile on its market and its economy lies on the rate of adoptors. And most importantly a unique character of being decentralized that users can have self governing on self custodial with their funds holding on bitcoin.
So I'd give them the chance to air their views about these unique potentials of bitcoin if being compared to our usual traditional currencies.

 

This is what my speech will look like

Hello distinguished members of the parliament, it is with great pleasure that I speak to this honourable house today regarding bitcoin. As we all know bitcoin is one of the greatest innovation of the 21st century. It is something that we have kept neglecting as a country for too long. And now it visible that we have been making mistakes all these years and I wouldn't want that mistake to keep happening.

It is high time we join the rest of the world that are embracing this technology since we cannot do anything to stop it. We can't remain in our ignorance forever. There is no escaping the reality that this bitcoin has brought to the world. Let us position ourselves now that is still early.

I believe there are lots of benefits that bitcoin will bring to us as a nation. It is the right time for us to make the right legislation about bitcoin that will attract investors to our country. With the population of this country, bitcoin will revive our dwindling economy.

If I would have the opportunity to talk with out legislation then I would simply ask why they don't want to accept BTC, why they not already given the green light to crypto. After getting some answers I will try to convince them by telling about how important regular permission is for the bright future of country's economy too.

People are still trading, and losing/earning from crypto why governments have not stepped into this field already and announced that the crypto is legal in our Country.

I would say one thing. Bitcoin/crypto is a financial asset just like any other financial asset and it shouldn't be discriminated. The government should treat Bitcoin as a normal financial asset and it should respect all BTC investors, traders and HODLers. However, all the pump-and-dump shitcoins should be banned by the government and their developers should face serious consequences. All the crypto scams that involve Bitcoin payments should also be hit by the law, since they have nothing to do with the true nature of Bitcoin. This is all I want to say.

Bitcoin, as a technology to self-custody one's economic energy is a basic human right. Bitcoin = freedom.

If crypto is given as education and generations grow up with this knowledge, then a good step has been taken for Bitcoin. An educated individual can contribute to the use of things that are good for society. Many politicians do not know much about cryptocurrencies and blockchain technologies. If they had received education on this subject in time, crypto would have developed even more. It is never too late for anything, only those in decision-making positions need to be informed. If they are informed about cryptocurrencies and blockchain technologies, then the state's view of Bitcoin will change positively.

Time is always positive for Bitcoin because the number of people learning about Bitcoin and its technology increases as time goes by. There are politicians among these people.

I would tell them to look at Bitcoins success and wide adoption and how it promotes clean energy and can be used as a non renewable resource or looked at as such and to create energy policies in favor of Bitcoin mining etc etc

If I had the opportunity to talk to my country's parliament or legislature about Bitcoin, I would first tell them how stupid they are, I would tell them that you are killing us with your stupidity.

After I give a long speech about the unique features of Bitcoin (which they will understand nothing of course), I would respectfully ask them to officially accept Bitcoin in our country or at least allow people to own Bitcoin legally.

Of course, I would not get any answer because these old senators would be asleep in their seats as they usually do in all official parliamentary meetings.

Maybe some funders would be interested because of what you would do and how much attention you brought to the whole concept
