Bitcoin is not for everyone, but we cannot over-emphasis its benefit. For awareness' sake, it is good to talk about it but not enforced it. Am not sure that Bitcoin's popularity is enough as we speak also your growth in Bitcoin should convince and want to make people invest willingly.
I want to believe that the forum that enforce people to join Biotcion has seen all the benefits but the approach shouldn't have been to force but enlighten them. It is important that you talk about it AND afterward encourage them to do their research.
