I have had people say things like that to me, not that I'd label it a problem. But I can certainly understand where this is coming from. When I was much younger, and still under the influence of the religious views of others, I recall hearing about the "Mark of the Beast" and, probably more than 20 years ago, had discussions with people about implanting chips in our bodies to use as money. I used to tell myself, "No way! I'd never do that. I'd die first!". I'm much wiser today. Most people aren't.

When I look back at all of the atrocities committed by mankind recently and throughout the millennia, I find that most of them were done in the name of religion. I can see time, after time, after time again, where people were basically brainwashed into doing what was right for the religious leaders but far from righteous. I can see now how a prophecy of something like Bitcoin could scare these leaders. I can see now why we might be lead to believe this is the Mark of the Beast and should avoid it at all costs, when really it's just a matter of self preservation for the unrighteous leaders of church and state.

As far as the "problem" goes, don't worry about it. You cannot argue with irrational people so don't even try. These people, as nice as they might be, are sheep. They have proven that by their current belief systems. And just like sheep, when the world begins adopting Bitcoin, they too will fall in line. Try to find better people to have philosophical discussions with and stick to talking sports and weather with these types.
