The last part of your statement is another realistic situation that is of great importance. Some people are just good at introducing poeple to something but leave them to wonder around and find a way for themselves. And sometimes, before they understand the system and adjust properly, they have lost something or scammed by fraudsters. So, its best they follow them up as mentor, showing them how to go about it and ensuring they go through ithe process and become strong enough before leaving them to fend for themselves

I must confess that I have learned something new from this thread that will help me to be comfortable to hold Bitcoin till am satisfy to trade out my Bitcoin. I don't think I will recommend Bitcoin to my friends now because our government hate Bitcoin users and it can make government officials to block all your bank account if they discover any decentralized transaction in your bank account. Even though I want to recommend anyone to Bitcoin and other cryptocurrencies, I think my family members will be the first people I will like to introduce to Bitcoin.

Ok, here's what I can add;

Tell them not just the pros but the cons also: Bitcoin investment is not all a bed of roses, there are up and down times too.

Let them know it is not a get-rich-quick scheme: Bitcoin investment is an investment and not just some ponzi scheme where you put in X amount and you get a ROI of a certain amount every week or month. So many people do have this misconception. I've had so many of my friends and relatives ask me this whenever I tell them about Bitcoin, "How much will I make after a month or a year time if I invest so so and so amount".

Let them know is an investment: Bitcoin investment is an investment unless you want to be a trader, but in as much as you're investing, you should have that mindset. Investment is a long term plan, just like investing in stocks, real estate, a business or startup e.t.c. it is long term, it takes commitment, patience and good financial plan like DCA and others.

I've linked that tip. I'd add that it is often a good idea to imagine a worst case scenario. What if you lose all your Bitcoins due to a hack? What if the price of Bitcoin goes to 0? What if I lose a big part due to a future threat I didn't take seriously (e.g. quantum computers if you reused your addresses)? And what if I get incapacited, e.g. very ill, can I still access my coins?

You can imagine several strategies to deal with these losses. Sometimes the conclusion is to invest less (if you've not much money you can afford to lose), sometimes it's a better prevention strategy (what could be my reaction to a quantum attack on one of my addresses? Shouldn't I have several addresses for HODL to be safer? etc.), and sometimes it may involve completely different actions, like selecting someone from your family & friends to manage Bitcoins in the case you're incapacited.

Agree sugar coating bitcoin to someone who has heard a lot on news that bitcoin is a scam, will likely think you are trying to lure them into something, instead explain what are the advantages and disadvantages they will experience when they make an investment into bitcoin.
I have been telling to my friends and relatives what bitcoin is, but they never listen to me but that's okay because now they realized they made a mistake, and told me they should have listen before, now they are asking me if they are still not late, my answer is try to learn first how bitcoin behave then decided, some invest but some are still thinking but thats not my problem anymore, I already introduce it to them.

Job, Job and Jobs.

Make sure your friends have one, make sure they are making good amount of money and they can afford to DCA into Bitcoin, there is no successful Bitcoin investor in this time without a source of income, it's a no no if they have no Job.

I personally would compulsory a airgapped device for my friends, if we want to do some testing we can use Electrum or Unstoppable wallet but hardware wallet is very important right now than anything else.

Through trading, no matter how much money or bitcoin they have at beginning of trading, they will quickly or gradually lose their money or bitcoin with time. Quickly if they trade with leverages, gradually if they trade with spot but endings are the same as losing all or most of their bitcoin.

Job is important to have money for life and people can find jobs in cryptocurrency industry or in other industry. If they want to find some jobs in cryptocurrency industry, welcome to Cryptocurrency Job List.

That's not your problem anymore. So far, you didn't sugarcoat your words about Bitcoin to them and they invested on their own will, for those who invested. And whatever comes up after their investment in Bitcoin, nobody is holding you responsible for their losses or mistakes made in the Bitcoin accumulation.

For those who are yet to take the bold step to invest in Bitcoin, that's their Bitcoin to worry about, not yours because you are busy investing through a DCA strategy

Yes I agree with you. I would like to add one thing to this, we often take refuge in many wrong people. For example, I want to know about a subject and I go to a person who does not know anything or knows a little and with that he tells me some of his own wrong knowledge. We all have to protect ourselves from all these people. There is a saying that a half-knowledgeable person is very dangerous than an ignorant person. So we have to know the things very accurately that the person we are going to knows the right information or not.

We have to note one thing, if a person tells us something then it will never be a right decision to believe in that subject immediately. We have to first do some research about that subject and if we find something good after researching then we can take that approach
