Although within this community Bitcoin is practically the only currency in which everyone believes, just look around a bit and we will find thousands of people who think otherwise.
At this point I wonder, what reasons should we give these people to make them realise that Bitcoin is a right choice? The first argument that comes to mind to convince a person who is sceptical about Bitcoin, is first of all that with Bitcoin you no longer need to delegate the custody of your money to a third party (banks, mutual funds, etc.): you are the master and you hold them. What else would you add?
At first I use to think this way, about ways I can use to convince people about bitcoin and why they should start making use of the digital technology, haven understood and benefiting from the currency myself. But I found out humans are hard to deal with for what they didn't on their own volition gained interest.
Some person's can attest to how they were later accused by those they convinced of investing in bitcoin and the market didn't go well as it was explained to them maybe because a dip happened after they invested. Now you never explained this part to the new person when you were trying to convince them.
There's no better way than to allow your success speak for you stead of spending energy trying to convince people about bitcoin. Why not divert that energy on ways to increasing your success.
