If bitcoin is being controlled by particular set of people by now bitcoin would have gotten to hundred thousand, and the existence wouldn't have take this long, because people of different kind could not trust bitcoin when it was newly invented, so I know very well that bitcoin people condemn it and later same people that condemns it are same that have values bitcoin later, don't believe in criticism mostly when you have the passion on bitcoin, since the Year satoshi introduced bitcoin partially it has gotten a milestones of fifteen years if I'm not mistaken

It’s so true there are so many misconceptions , most are held from word of mouth he said she said and aren’t based on anything but fluff. Those folks don’t do their own research or know the first thing about Bitcoin they just hate it the same way folks hate Donald Trump

Bitcoin isn’t controlled by any single individual or an entity, most persons knows that. Bitcoin isn’t subject to any form of censorship. It’s the one truly decentralized asset in cryptocurrency.

It would have been really nice to hear what backings he had for the things he said of Bitcoin. I suppose those where the catch go better his understanding.

Your friend wasn’t going to learn nothing from an argument, just as you learned of his ignorance and backed out due to misconceptions, he obviously would be so focused on being right than wrong and learn.

I'm here for a little while now so i think the wrong notion about bitcoin shall have to be addressed by a combination of education and healthy debate. Most of the misunderstanding comes from ignorance of how Bitcoin works. One should give clear exact information, explaining that Bitcoin is decentralized and managed by distributed computers, not just some powerful central entity. It is secured with approved mechanisms like Proof of Work and principles of cryptography. A lot of misinformation can be corrected by patient talking and evidence-based explanations, by listening to the other party's concerns. Another way to correct the bad information is by appeal for critical thinking, whereby others are challenged to verify information through trusted sources. By focusing on these strategies, you can help dispel myths and encourage more informed conversations about Bitcoin.

And we can't avoid to encounter those misconceptions or misunderstanding since not everyone could understand easily bitcoin and what they only believe on those narrow information they know especially if they don't have further interest about it.

If they could just learn a lot of things and try to deep dive on the information they could possibly search for sure those word scam towards bitcoin will never came into their minds and for sure that they provably know that bitcoin is currency and just been used by those scammers online. But many choose to be lazy to educate their selves that's why those misconceptions happen to those people who don't have knowledge about bitcoin.

Listening to their (wrong) arguments and correcting them makes them feel that someone cares about them. 

This is not wasting time, but rather helping these people know the truth and leave the wrong information they have in mind. It's up to them to accept reality, but as a concerned citizen, I don't think we leave them like that; instead, we help them to be right. An open-minded person is willing to accept corrections for their mistakes and is willing to change their beliefs. There is no instant change that happens; they will soon find it right and go with it, having the right information in their heads. 

Well, you already said that it is only the lack of Bitcoin knowledge that causes some individuals to have misconception about Bitcoin, some persons don't have knowledge about Bitcoin and some persons don't like Bitcoin because of it's volatile nature. The major cause of Bitcoin misconception in some people is the lack of proper Bitcoin knowledge.

Yes, among of them is not having the Bitcoin related knowledge and still not wanting to learn about it. Bitcoin came into the market with criticizers right from the beginning, while many has pathed ways with such doubts, also some set of them who still retain those hatred for Bitcoin and they will continously try to prove their point to others but if anyone could be smart enough to not just accept what he/she heard and try to carry out further researches, only then can we clear those misconceptions.

If bitcoin were centralized, what would make it so attractive and attract our attention?  If bitcoin is centralized , what makes it different from other altcoins or fiat currencies? There is no denying that until now most of us have been more focused on its price than anything, but bitcoin's success is entirely dependent on its decentralized nature. Because if it is centralized, it will be destroyed or become useless from the beginning . Basically, bitcoin has been decentralized from the beginning, it is not under the control of anyone including its creator .

Bitcoin can be manipulated because it is so small compared to other assets , but if someone thinks that the bitcoin network is controlled by underground forces , I will not believe it .

When someone does not have the desire to learn about Bitcoin and only hears about Bitcoin from those who have failed in Bitcoin, of course they will never understand Bitcoin well and if they can take their time to learn it, of course they will be able to understand Bitcoin well and also they can use Bitcoin as an asset that they can invest in.

However, for some people who hate Bitcoin, of course they have unpleasant experiences, both losses in investing and trading, and this certainly happens because of their own mistakes who do not want to learn first before deciding to use the asset to invest or trade, doing research from what we hear from other people is certainly very important because someone could only share the mistakes they made and they do not want to learn the mistakes they made.
