From maybe 50 people I know personally, let's say, maybe 40 using Internet.
From this 40 maybe only 10 using Internet for more serious things like online shopping etc.
How many know about Bitcoin?
I think 5-6.
Others just don't care about such things.
It's still reality and we have to be aware about it.
I had the same experience as you had and I agree with you. But bitcoin is just beginning and we need to see the bigger picture. Take a look at the coming 20 to 30 years. Bitcoin will be famous and will be used widely more than today. The volume of transactions will be massive if the code and algorithm is well maintained till then.
Everyone has the same experience as we all know bitcoin is not really that much popular in practical world but it is just there on internet and someone who is not always involved in internet does not know anything about it, in my case if i ask a half of the people around me i'm sure none of them will say they have even heard about bitcoin, so yes, "Not everyone knows about bitcoin."
That said I think a lot of people are unaware about bitcoin.Last month I went to Bank because my funds coming from Paypal was put on hold by my bank.To my surprise,bank staff was not aware of what PayPal is and how it works.
When peopple working in financial sector doesn't know about Paypal,how can they be suppose to know about bitcoin?
