I always find people who think that Bitcoin or cryptocurrency assets are busting money and sometimes there are people who always assume that investing in bitcoin is fraught with hacker risk.
Why is investing in bitcoin be considered a fraud and if any one claim these they know anything about bitcoin.on the other hand I cannot assume that their opinions are wrong, but on the other hand I cannot justify their statements.
If you think that their opinions are right then why you cannot justify that statement 
.what do you think about finding people like that and how will you react to them?
You cannot do anything for people who think like that and it simply because they are not interested in understanding the facts and hence there is no point is making them understand anything.
