Why should we believe in crypto currency after this crash?

When I talk with older people about Bitcoin or any other crypto currency, it seems that I’m talking in another language. Most of them don’t know anything about it and many of them couldn’t see how close to the future this is it. Once, a person asked me why he couldn’t say that a key worth $2000,00 such as Bitcoin hahaha- I answered that he could, but people and the marketplace need to believe on that. Anyway, when the computer was created, many people did not believe that it was going to become something present in our lives and that it would be something as useful as it is today. After all, they were so big they could barely fit into a building! So that is one of the reasons why we should believe in crypto currencies even after all this crashes and after many places posted that is the death of Bitcoin, Ethereum or any other one. Steem for example have a huge potencial but we need to not only share this social community as well as encourage the ones who are already here to participate more and improve their view about Steem. We need to post things like “ I liked of how you write texts, you should write more” . Some people still don’t have a lot of upvotes but they are not posting too much things to become known. Of course we have a lot of texts that only talk about bullshits but at the same time we have very good writers who only need a little help and a small incentive to become great bloggers with interesting subjects about various things.
