People will always have their complain about what ever they are not comfortable with at that particular time, their are still people that are still criticizing bitcoin but that is even their problem, and few months back their were people that were making comments that bitcoin is the cause of some currency depreciating, which is not true I even feel like bitcoin is the one relieving the pressure on some currency since it's like an alternative to spend but no some are busy condemning bitcoin.
Those that want to change their mindset towards bitcoin, that is their decision to make because I don't think anyone should be forced to do anything, because at the end of the day you might want to help them and you will be the one they will blame if they don't end up making profit, and all this is actually because they don't have knowledge of not it would not have gotten to that extent, and any one that won't add any value should not be blamed they don't have knowledge they would have given much value to bitcoin.
