I live in rural area. We currently have electricity and internet facilities here. I use bitcointalk. I know about altcoinstalks from bitcointalk.
Now I want to tell my younger brothers about altscoinstalks. But I can not understand how to start.
What i will advise here is for you to start at least from somewhere, tell them how you got to know here, what you have also learnt and discovered about this forum, this is just a discussion platform about cryptocurrencies in general, so they will need this platform together with other materials in learning about cryptocurrency, give it time and teach them in your own capacity, then give them other resourceful links to help them go through.
If am the one in this , I think anything that would be done about spreading awareness to my friend and family will be strictly done under the influence of knowing if they are interested or not because some people I have encountered are really not that interested and it's we that forces these knowledge on them and the reason why I say is because of all the negative expression and reactions I have received from trying to share and bring someone that's not totally interested in crypto stuffs so I believe before you share to brother, know if they are because you might just end up regretting your actions.
I don't know how you explain stuff about crypto to your family, friends, and so on. But based on your explanation, you seem to be the type of person to force other people to do the same things you do.
If you don't force them, of course, you won't end up regretting your action or receiving any negative reactions from anyone you explain crypto, because it's more on having an opportunity for them to earn. That's an incorrect way of sharing knowledge with anyone, you will only start sharing the information you know once they ask you or if they show any interest.
Don't do it like talking to someone you know and explaining them out of the blue. Aside from they will never understand anything, they won't hear anything you will say.
