You do not need to force yourself on someone to believe you, just do your part and leave the rest. But, no matter what, not all your friends, collegues and family will neglect it, only further explaining what you know to those that embraced it. With time, with positive news from you, others or few from others can also like and embrace bitcoin.
One thing to keep in mind is to not promote crypto as an "easy cash" kinda thing, people usually lose interest with that kind of explanation. I always tell my friend that crypto is an investment.
