It does matter how far, its matters how well. We will all smile let's keep advertising Bitcoin to the world, encourage people to invest more and together we will the good future we desires.
Yes we should do this because when more people will invest the network will grow and we can expect BTC adopting inany areas.

Doing these actions seems to suggest that we are part of a group that is excessively idealizing bitcoin. You cannot coerce someone into accepting that by increasing adoption, the value of bitcoin will likely rise over time. Because doing so appears to be promoting a typical pump-and-dump scheme.
When someone close to you asks you to give a detailed explanation of bitcoin, the only thing that anyone can do to adequately promote it is to help them. Just be willing to share your knowledge, and refrain from overtly advising others to buy bitcoin.
