If they ask about the investment potential, I will briefly tell them about the potential of Bitcoin and how risky it is - maybe they heard how Bitcoin can give them profit, and explaining the basics of proper Bitcoin investment to them might help them navigate the Bitcoin investment. Since many newcomers have the wrong mindset when they invest in Bitcoin - they think it can make them rich in a short time - I will tell them that it is risky and they must have proper knowledge to start investing in it.

I would tell him to go to Bitcointalk.org and start off by reading the pinned posts in each of the boards, especially Beginners & Help.

Bitcointalk really is the best place to start your Bitcoin journey.

Let me start by saying, after every conversation with the friend, still advise him to DYOR. It is by this you can exonerate yourself if things go south.

If I were you, I would first focus on the enticing part, which is the success possibility in Bitcoin to catch his attention. If the friend is interested, I can then proceed to furnish him with all the possible books, links and guides about Bitcoin and will still tell me to surf the internet better on it.

By this, the friend will naturally learn everything about Bitcoin without you stressing yourself too much.

I would say the same thing I always to Every beginner, Bitcoin isn't a ponzi scheme or a way to make you a rich in a few days. It takes time and discipline, only those who are patient and consistent enough can reap the benefits of it. As beginners it's important to focus more on gaining knowledge than trying to figure out how to make money, in the crypto space you must learn before you can earn.  Take your time to understand what crypto is all about, learn about how the market moves and when you are acquainted with some important things then you can think of making an actual investment. Knowledge, discipline and consistency those are the key things you need.

The first thing I will tell him is that Bitcoin is open source network no bank or authority can control it. It's a financial freedom as well as it has a possession of huge profit. Bitcoin can make you lose along with huge profit because of its volatile nature. Do your own research to invest in it. In Bitcoin we can organize profit through investment and trading. Those who have experience can manage profit in the short term as well as in the long term and if someone does not have that much skill, then they can organize their profit in the long term. It means that the risk is less in long term investment.
 
So this means that Bitcoin is not only a digital existence. its also has the potential of a lot of value in the long term perspective. But taking into account all the risks and hurdle, we should invest enough money in it that we don't risk your daily routine life by losing it. And the privacy stance should also be deeply figured out so that you don't get harmed later.

Yea that is the real truth about it, it's essential to let them know that investing in Bitcoin without having a side hustle can make you sell your Bitcoin when you are supposed to sell it. So for you to be able to hold onto your Bitcoin investment is by setting up a good plan for yourself, so that Incase of any emergency you can be able to settle it without touching your Bitcoin investment.

You don't have to tell him tech or even bitcoin itself. Your answer to his question should depend on the area he is also asking. You don't have to swim in the ocean without direction. Your friend have to ask what he wants to do. Is it investment, trading and mining. And when he has asked base those subtopics then you also give the answer base on the area or the field. That is how I have been doing. I do don't answer a universal question but it should be specific so I know what I will say but if he asks a universal question then I will be talking in and out of point.

Majority of those to whom I told about bitcoin, dont believe in it, and even stories about $5k>$100k in 3-5 years with examples did not inspire them. I cant explain why there is no trust in Bitcoin from them. They say it is a joke. However, they better believe and spend time on Hamster or other tap or click primitive games, than buy any amount of Bitcoin and hold.

A person should be willing to go a bit deeper and crave knowledge about Bitcoin.
If he isn't - that's his loss. It's unfortunate, but it can't be reasoned with, mostly.
