So we have to focus on 3th group to make them understand what is the philosophy behind Bitcoin. We have to introduce the bitcoin and try to help them to understand, trust and use Bitcoin. people blongs to the 2nd group will never defend Bitcoin if they saw a price down.
The problem is that most of them don't want to know about bitcoin. They are usually lazy or too stuck in their own ways that don't want to change. Also they don't want to see the corruption in the banking system they use so the incentive to use bitcoin is not there for them (which happens to be the reason why some people only care about the price).
I blieve that cryptos will never die.
I think you mean bitcoin because cryptocurrencies aka altcoins are dying every day.
