Most of the members here or people involved with crypto will take things positively only. But the opinion of other people also matters. If we cannot convince those people to invest in crypto, it will not grow the demand for bitcoin.
No need to convince people to invest in Bitcoin, Bitcoin exist since 2008 and there are already a lot articles or videos discuss about Bitcoin, if they're want to invest in Bitcoin, they can search any information related to Bitcoin via online.
I would choose to be silent, if people are invest in Bitcoin because someone convince them, they would call Bitcoin is scam if Bitcoin price not go like their expectations.
