As long as the person respect your beliefs I think it's okay. It's a shallow reason to pull out your relationship with someone who have different beliefs in you especially if that person is your childhood friend or is really close to you. I understand that we should choose the right person carefully if you are going to make him as your real friend. But it never a good idea to end your good relationship or change the way treat them just because they are against your belief. If only they embarrassed you for what you believe, I think it's reasonable to stay away from them. But before that happen, give them enough time and be patient, maybe soon they will like Bitcoin.

I think that it's not my duty to prove anything to anyone. I try my best to educate people and introduce bitcoin in their life but instead I get cynicism, laugh and people say that it's a bubble that will explode. Time goes on and all we see is that bitcoin achieves new all time highs and price is going to the moon. Now I don't talk about Bitcoin unless I hear it from someone, I just shut my mouth because it's not really my duty to educate others and it's not really nice to get cynicism back.

Yes, it's good when you have people around you who are optimistic and give you boots but I think it's not good to hear only positive sides and don't hear talk about negative sides from others. We need balance in life, I believe this.

Simple is that don't share your financial matters with other especially with those who talk behind you and comment negatively about your success. We are earning for ourself not for others therefore we have no benefit whether anyone is investing in bitcoin or not. Money is your so responsibility will also be yours that how and where to use this sum.

We should not talk to everyone about our Bitcoin's investment because hackers are always present here which can steal all your data and also other people will not consider it to be profitable so your word of convincing others will have no effect at all. If someone is interested in Bitcoin's investment then he will ask you first without your convincing approach. Don't think about negative thoughts of others because everyone will think differently, you will find bitcoin as a profitable asset but others cannot therefore leave every other person to make their own decisions.

They won't understand in a year or two, because they won't know what bitcoin is or try investing in it in a year or two. If they tell you, for example, how delicious fugu fish is, but don't tell you the details and don't let you try it, will you know what it is and what it tastes like? It's the same with bitcoin. So it is necessary to educate people, tell them about bitcoin, and then, knowing a little bit what it is, they will be able to make their choice.

However, truth be told that everyone is not meant to be the same as you and people not agreeing with what you are saying doesn't mean that they too don't have a good reason for that. Moreover, there are a lot of people today that don't like what others don't like and most of them are doing well so far.
For me, I can still keep those same people as friends only if they mean no harm to me or if they are not like a threat to my investment. Why, because we can learn from each other, they too might know what I don't know, and I can still learn from them and they too can learn from me in one way or the other.
Sometimes, those people that are closer to us are the ones that mean harm to us. There is a popular saying in my locality that says YOUR BEST FRIEND IS YOUR WORST ENEMIES and it is true because, when they are closer to you, they are getting more information about you and your assets.

We would just stress ourselves if we keep allowing those negative opinion coming from people doesn't know or didn't like to know about bitcoin since for sure that they will be close minded on it since they don't know anything about bitcoin. Maybe I will just simply continue on what I am doing and will not have time to explain anything to them about what I do. Just letting them to see the profits I made by investing on Bitcoin and crypto then its up for them if they try or if they ask since I will answer it on the most basic way.

Maybe they might really get interest about it when they see bitcoin bull run is already happening and to many people earning a lot of money coming from it. The profit itself will explain anything and for sure those skeptical people will might get interest about trying since they also want to earn that.

Let them be.
Some would be frustrated trying to win their relatives’ favor of this investment but on my end I’d choose not to encourage others to also do so. One reason is the risk; I know how fast changes take place with market behavior and I don’t want to drag other people to something which has risk. If ever they’d have the initiative to invest then I would be willing to guide them. I am avoiding conflicts; non crypto investors would normally be impressed of the profit potential but not the risk. And if ever things would be problematic I would be for sure the one to blame if ever I would choose to encourage them to invest in this industry.

Usually, I am quite different, and I think differently. I'm not scared and don't react when someone doesn't believe my beliefs. I just let them live with their beliefs. I don't try to convince you to walk on the same path as me. Because it's related to financial investment, if something goes wrong, it would hurt me later. How can we think that everyone's beliefs are the same? All the individuals won't be interested in Bitcoin so quickly. But when they see your success, they will realise their mistakes, and they will respect your beliefs. I have real experience; one of my friends didn't believe in Bitcoin until six years ago. A few days ago, he told me he was wrong. He should have a better life if he became a bitcoin investor.

 
Verify according to when i learnt of Bitcoin, I was comfortably in doubt and ignorant about it and it was hard  believing its reputable state of potentials else I would had been into the system since longer time ago.
So, I still believe there are people as my formal belief about Bitcoin so I could handle their negative sabotages about Bitcoin and I was able to ask them let me concentrate on my journey without trying to incite me with some negative anxieties along my Bitcoin quest.
This is one of my aspirations of creating this thread that talked about: Walking with those on the same mission as you if you must conquer" https://bt.irlbtc.com/view/5458884.msg62512588#msg62512588

 
You don't push and pull out of people just because they don't agrees to your believe else you would create unnecessary instigations and that is assumed of being biased. Knowledges and beliefs are in diverses so those of your friends is either not a waste being around you because they may hold potentials to offer outside your Bitcoin investment.
But you may decide to pull out of people who doesn't want your success and not just because they are not of same mere belief with you else it natures your you negative rapporteur and segregations sabotages.

 
The truth is that it is not healthy enough to convince anyone about Bitcoin but can only talk to them about it as much the Bitcoin markets doesn't require any form of marketing skills to attract one for personal interests of making profits.
They may doubt you in as much they are adamant and ignorant to the system but does not mean they are bad people but at the virtue where you are being expected to fail is where lyes being an anti-success and should be avoided.

@ OP, I have come to realize that if you don't talk about Bitcoin or giving one the chances to argue with you about Bitcoin no one would stress of it with you.
