There are many factors that make many people still say negative things about Bitcoin and even mock it, namely because they do not really understand Bitcoin, ignorance, reject change, have experienced losses due to their own mistakes and also because they were late because they did not believe at that time and after they found out that many people or investors became rich because of Bitcoin they became jealous. And all of that is human nature that has become commonplace.
So, just ignore it because in the end they will definitely get involved because I experienced it myself, there were some of my friends at that time who always denied talking about Bitcoin and after Bitcoin proved its bubble and also saw my significant changes in terms of finances and circumstances they secretly got involved and I am sure those who are still negative about Bitcoin will sooner or later be tempted and get involved and this will continue to exist and become one of the unconscious Bitcoin adoption processes because it is real.
Some of the negative things you hear about Bitcoin is not only about mistakes people have made in the past or stuff's like that, some of the negative news that have gone round about bitcoin, majority of them are government sponsored, at least at some point the media was gagged about giving positive news on Bitcoin in some countries, some countries up until today still have serious sanctions on Bitcoin, so all of these put together have snowballed to this negative perception most people once had about Bitcoin. So at some point, I personally found out that whenever most people want to invest in things that will liberate them financially, the government will frown at it or spread negative perception around it especially given the fact Bitcoin itself is decentralized and it's way out of their reach to control and manipulate. The good thing is that, Bitcoin has proven them wrong and has even surpassed their expectation way beyond what they could even imagine.
I agree with you mate because the government always tries to witch-hunt anything that wouldn't be beneficial to them and due to the decentralized nature of bitcoin makes it difficult for them to intrude in people's transactions. I also agree that the government can also use individuals to spread negative news while their motives may be to cause panic and when the market falls, they secretly buy bitcoins are cheaper price without the knowledge of the public, the government have top secrets that only the cabals within themselves knows the games they play to their own selfish interest and just in recent time, we have witness some manipulations in the market which also comes from some negative decisions the government made so whoever that is investing in bitcoin should not pay attention to negative news. Why should one be afraid of the outcome of bitcoin when they have already invested within their level of discretion. Bitcoin has passed the stage where any negative news from the government or any individual or institution will cause long term price actions, the market can survive naturally without any influence of any party or the government.
