But of all the discussions I've had with co-workers, friends, and relatives about bitcoin, it seems to fall on deaf ears. In fact, if talking to more than one person, it seems to be almost a witch-hunt on how bad of a ponzi bitcoin is, and how 'it is backed by nothing', etc.
You have to be flexible with your talks about Bitcoin to your co-workers, friends and relatives. Not all of them will show attention in what you said and not all of people actually listened to your speech will have interests in Bitcoin.
Who have interests in Bitcoin will ask you more especially after they go home and do their research.
Who don't have interests in Bitcoin, please let them be. Don't waste your time on them. They are free to listen to you or ignore you and if they think Bitcoin is a Ponzi, let them be.
Now I realize that this reaction comes out of either fear, ignorance, or not knowing enough about it. But no matter how hard I try to educate someone on the positives, it falls on deaf ears with some.
When time comes, they will return to ask you but I believe when time comes, you will no longer have interests to educate them about that.
