I personally just don't randomly talk about bitcoin. I just usually mention bitcoin or cryptocurrencies in general and what they can do if someone I'm talking to asks what my interests are; and I only go slightly in-depth if the person is genuinely curious about it.

How do I promote bitcoin? I tell the person/people about it's main selling points/advantages: being decentralized, peer to peer, giving you total control over your funds, those stuff. I almost never talk about bitcoin as an investment, as I definitely wouldn't want them to look at bitcoin solely as an get-rich-quick scheme like most people do (and also because I end up sounding like someone shilling a pyramid scheme). If they become really really interested, then chances are they're going to put in money at some point. I prefer them having to decide themselves to buy bitcoin instead of me pushing them to buy bitcoin.

Basically for me, what people need to do is just by word of mouth. A lot of people need to spread positivity about the advantages of Bitcoin and also give evidence why it is very beneficial.

Bitcoin is already at the highest peak if measured in terms of popularity. There are can be  social media campaigns that can spread the awareness or any sort of latest methods that are used for publicizing cryptocurrencies. Launch of new programs with bitcoin that supports new inventions and other technical advancements.

I'm let my friend and family know that I'm richer than yesterday and when they interest , they will start asking.
Yes, I'm explain about bitcoin in simple way, as simple as possible so they can understand the advantage and disadvantage about bitcoin.

Of course I'm tell them not just the profit but I'm also explain that bitcoin value is extremely volatile like current situation for example

To be honest, I am against promotion because it creates some kind of suspicion in the mind of another person. We don't have a very good reputation of the crypto industry, so instead of using the word promotion, I would say that we should always be there in order to explain Bitcoin and cryptocurrency to anyone who is willing to explore further information about it. We should not take any artificial efforts in order to attract others towards Bitcoin, the user base is growing since inception, we just need to share genuine information with that growing user base and clear their misconceptions.

Always shilling bitcoin until I die 

yes, I have promoted the crypto world, to all my family, neighbors and friends.

crypto always gets a positive response from them, my theory and simple explanation changes their mindset, but unfortunately, they have difficulty applying the technology of this blockchain.

Anyone i meet who expresses the remotest interest in crypto i explain
what bitcoin is and why it was created in a very simple language. If
That person wants to know more i use simple language to prompt them
to investigate further themselves.

I promote bitcoin by simple language and have "converted" a few
people over the last 12 months, they are still involved through the
highs and lows.

I promote bitcoin by explaining bitcoin through conversation to those who are curious and interested in learning bitcoin.

Normally I only briefly explain first especially the fact that I get from this, if he is interested I just explain it thoroughly and elaborately so that he is interested and will be useful for himself
