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.
That's a good explanation, but mostly of the people who's playing safe for their sake since they've introduced Bitcoin to others so if something might happened like losing funds they might get blamed which is not literally his/her fault. That's why they introduced it by giving them the basic knowledge of the Bitcoin's pros and cons since it's volatile and have a risk involved.
And I'm with you, since this forum literally named as "bitcointalk" so it would side to the Bitcoin like their benefits to hook more people to join in this industry. Still it's true that there's a lot of opportunity in this industry if you only have the proper knowledge and skills, and if you've already build up your mental and decisional making since you need to think carefully for every decisions you make.
