If your client is interested in learning about Bitcoin, you can explain everything about Bitcoin to them. But if it happens that after you share Bitcoin with him, he misunderstands you or thinks you are wrong, then there is no point in introducing him to these things. You may think that by discussing Bitcoin with your clients like this you will increase the popularity of Bitcoin but if your discussion turns out to be bad for you then I think there is no need for this discussion. Bitcoin is already a very popular digital currency and its popularity is increasing day by day so do not discuss Bitcoin with others at your own risk.

If the discussion starts and that client starts to ask some questions, he should be prepared for it. But not too fast that he'd be like an advisor about investing on it. He can give scenarios that will enlighten the mind of his client for him to introduce the idea. Always put a disclaimer that you're only educating him and not convincing him of investing. I've been there and done that but not with a client but with close friends and families and they thought that it's an easy thing to understand. And, all they think about is all profit, I've told them that they'd be in profit if they continue to hold Bitcoin in the long run.

But, that's not the end of it, they are impatient, hasty and greedy. That's why it's not just all about talking to your client as if he's going to invest quickly. That person might even blame you after investing when the portfolio's value is going down. There are types of people that are like that and they won't be regretting trying to drool you down because you're the one introduced it to them. They'd make you feel responsible for everything that's happening in the market even if you've clearly told them that you have in no steer to the market.

In reality of things. You don't convince someone to start up something when you have less knowledge of what you want to convince them to do. You only convince someone to start up any investment or business, when you have full knowledge about the ups and downs of the investment.

Bitcoin investment requires everyone to invest at their own free will. So that any losses made, the person won't have any blame on, but rather themselves. Convincing someone to invest in bitcoin, means that you will be hold responsible for their losses and misplaced seed phrase.

To avoid such future blame on your side, don't convince someone to invest in bitcoin. You can just tell the basic knowledge of bitcoin so that they can be aware of it, that ends it.

That will definitely be a good way to start, but to me, I will advise that before even going down to the history, we can start by giving the person education about the risks involved, how to handle them, and how to be protected from losing whatever they invest in Bitcoin. 
 
Then, making it clear that there is no guarantee of investment profit in a short time unless they are willing to hold for a long time, we can go to the feature of it and see what it could be used for and how valuable it can be too.

Come on! This is an old and classic question, which given the times we live in, is like telling anyone you know what Fiat is... let me explain, we live in times of absolute information available to everyone.

Then, no one is introduced to bitcoin, at least not the clients, that is, you may already be earning a future problem in something that surely does not concern your business.

Consequently, it is as the classic example of; how Fiat currencies devalue and you intend to explain that to your client before they buy your product.

It seems like a lot of advice has been mentioned by other users before me - sure, I agree basic knowledge and how the market works is something you need to share with him before he makes a decision to invest.

Remember that the goal of investing is to generate return - but investing is an activity that carries a high risk of losing money if potential investor never know how to minimize the risk. You can teach him basic knowledge including how to create secure wallet, buy, withdraw his bitcoin to the wallet and keep them safe. But here's the thing - he doesn't have to be an expert ^{[technical expert]]} just to buy or own bitcoin.

Bitcoin is a high risk asset, so you need not to convince people to invest on it and give him all the assurance he wanted to hear, because if his bitcoin investment will not work based on his high expectations, then you will be blame for that and you'll be accountable of all his losses.

Guide him while he wants to learn about bitcoin,  but always avoid convincing him because that looks more a scam to him if the outcome will not come out good and profitable on his part.

See Bitcoin is a public topic Explain to your friend about Bitcoin the same way you learned about Bitcoin. You should slowly explain the Bitcoin pros and cons to your friend and don't encourage him to invest too soon. Don't force your friend to buy Bitcoin if he doesn't want to.  If your friend has no interest in investing in a pair of bitcoins, don't ask him to invest against his will. However, one thing to remember is that investing in Bitcoin is a personal choice of an investor, so advising someone against their will is not acceptable in any way.

First, don't be too persistent in convincing someone to dive into the Bitcoin realm. The reason is, Bitcoin is volatile, and there is a risk of loss if someone does not really understand Bitcoin itself.

To use Bitcoin in terms of payments or anything else, both parties must know what Bitcoin is, how the system is and the risks and benefits. If only one person understands and the other party doesn't understand, this will clearly cause new problems.

Innovation comes from oneself and knowledge of it. If innovation is just an invitation or coercion it will only cause problems and losses due to a lack of understanding in this area.

In terms of speed and cheap transaction costs, perhaps there are types of cryptocurrency other than Bitcoin that are superior to BTC.
