It's safer to introduce Bitcoin to your friends and family and give them a general knowledge of what crypto is all about so that they don't get confused, but at times of investment choice, it's better to allow them to make their choice on which to invest in. I don't even share other altcoin knowledge and ideas with people; it's my personal way of playing safe in order to protect myself from the attack of investors who have made a wrong choice.
It is not bad to share your crypto knowledge with your friends and family members if they are interested to know more about cryptocurrency at least it saves them the money they would pay to register for some courses because I know a lot of people are running programs online where people who are interested to learn about cryptocurrency register and get daily tips but don't you think you shouldn't shy away from telling them the truth and the best investment plans that would help them to avoid losses in their investments, I think if you are helping someone who has little knowledge about a particular investment you could also suggest the best things for them if you have tried that same things and it worked for you. People make wrong choices as a result of lack of knowledge but I think helping people to suggest good plans helps them to learn and make good decisions faster.
Many times, among close friends and acquaintances, they try to gain knowledge from others. They are very eager to learn, but you may think that they are not interested in that subject or topics. That is why I think it is necessary to give knowledge about this to those who are close to you. Those who are interested may be interested in it from the beginning, that is why you should definitely try. There are many friends who, without getting any opportunity, are only trying to learn it online. If you have good knowledge in this concern, then they can benefit as well as you can get a good opportunity to expand or share the knowledge you have.
I have heard of a case among friends where a friend did a lot of online research to learn about Bitcoin but he did not dare to invest because of fear. Later he came to know about a close friend of his who had been holding Bitcoin for a long time. Surely if that person had given his friends a little idea about Bitcoin, they would have definitely learned more about Bitcoin. They could have benefited more.
