Why do you have to do that?
Trying to convince someone over something that the person did not want isn't right most especially when it's all about Bitcoin, don't force anyone to it, just explain to them what the technology is all about and then let them be, there is no point in convincing them that Bitcoin is the right choice, because if any mistake of investment is being made in the near future, you who convince them will be the one to be hold responsible.
@Ever-young such approach is bad in my opinion. well, I know a lot of people have their opinions but come on, Bitcoin is open-source asset design for public, everyone can take part in Bitcoin but the problem here is that you encounter someone who is
schecktical skeptical about Bitcoin, being
scheptical skeptical doesn't really mean the person doesn't want but either the person is in doubt if they can profit anything about from the technology, they are in doubt if their funds can really be save with Bitcoin investment and perhaps if you are the guy that is so knowledgeable about Bitcoin, you know how beneficial Bitcoin technology is, and you want the the sceptical guy to enjoy the same benefits of Bitcoin, of cause their is nothing bad trying to really make them understand what the technology is all about and the benefits they can enjoy. IMO, it's not bad to explain to a sceptical person and make them understand better
What else would you add?
OP, if I am in this position to talk to a skeptical person, first I have to educate the person about inflation and how inflation can reduce the purchasing power of bank notes over time and how money can lose value because the central banks can print more money any time they want. Then I will educate the person about the voluminous supply and circulation of bank notes and the limited supply of bitcoin and how bitcoin can attain more value because supply is limited and demand will keep increasing. Going forward, I will talk to the person about the privacy of having a very large amount of money they want to store in Bitcoin without anyone knowing their identity. With these few points and other things I will add, we can be able to change the person's unconvincing state of mind and become convinced.
