You can try to educate people or make them aware but the problem with those people who have fixed their mindset of bad image about btc it's hard to change and for me I am not into wasting too much efforts in convincing anyone that why it's good because until they make their own research and came to know about it they won't believe it.But in comparison yes there has been significant change in people thoughts about btc due to awareness and increasing adoption rate.You can always try to put some efforts but not feel bad if people are not into it because it's their loss in the end.
In fact, there is no particular need to convince those who have already formed their opinion about bitcoin, it is just a waste of time at the current stage. There are a huge number of people who still do not have enough knowledge about bitcoin, and they are the ones who need to be told about it in the first place. Moreover, to to be told truthfully, with all the pros and cons, so that they eventually get the right idea about bitcoin, and so that they do not lose due to lack of awareness. And then, with the growing number of those who will benefit from the use of bitcoin, even those who now have a negative attitude towards it, doubts will begin to creep in, and they will also reconsider their attitude over time.
