It is natural for everyone to have different preferences and tastes, and forcing someone to do something is never the right way. Especially when it comes to Bitcoin investment. Bitcoin is an investment that will never guarantee anyone a profit, Bitcoin is a long-term potential currency.
Now you have told your friend or anyone you know about Bitcoin investment, he hesitated to invest, but you convinced him to invest with a lot of assurance, and he invested as you said, now Bitcoin did not pump as you expected after a certain period of time (after 2 or 3 years), but rather it started dumping more, then he will become very scared, and he may ask you for his invested money back, and he will completely blame you for this. You may know that Bitcoin will pump after some more time, but at that time he will not believe you in any way, and will continue to be angry with you.
So never force anyone to invest in Bitcoin, you do not know whether Bitcoin will actually pump in the future, that is why when you force someone to invest in Bitcoin, and Bitcoin does not give you the return you expected after a certain period of time, then the entire blame will fall on you. You will only be limited to giving advice, never force. Let them make their own decisions by analyzing their own judgment, if they can really understand the possibilities of Bitcoin, then they will want to invest in Bitcoin on their own, otherwise you do not need to force them.
Mate well said, in regards to any investment be it Bitcoin investment or any other investment, personal decision surpass any external advise because Bitcoin investment specifically has they way it operates so any interested investor must take responsibility of whatever decision he or she takes to avoid blame, some people enjoy blame games as if they profit they will share it with other people this is why we shouldn't decide for people or persuade them to invest in Bitcoin, some people feel that as you invest in Bitcoin you will start profiting immediately not knowing that Bitcoin investment has a process that each investor must follow in other to scale through to the future.
Though I understand that some people are full of doubt and for me that's more reason why we shouldn't force anyone to invest in Bitcoin in the first place, the fact is volatility favour either ways of the market at any given time but at the early stage of some investor in the investment they may not understand such fact as such it may begin to make them shiver if the price eventually drops below the amount they invested with and the may be push to start blaming you for leading them into the investment since they do not understand the concepts of Bitcoin investment, mate your conclusions are right, i think it's a right thing if we don't persuade people to invest so that we will be free from blame if anything eventually occurs.
