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?
I think what you said is right, indeed Bitcoin has the advantage of being fully decentralized or not affected by third parties such as banks.
Even though Bitcoin has been around for more than 14 years and consistently shows its existence, in fact other people still don't believe or won't be able to just believe in things that are new to them like Bitcoin.
What's more, we only introduce Bitcoin to them only through our arguments without any proof of what we have gotten from our activities while using Bitcoin, it will not be able to convince them.
There are many factors that affect them not being able to believe in Bitcoin. Like the negative issue of Bitcoin it's a ponzi scheme or fraud or Bitcoin seems something complicated to understand for people who don't understand technological developments, and maybe there are many other reasons related to the high risk that exists when using Bitcoin.
Sometimes some ordinary people still think Bitcoin is a ponzi scheme or fraud and some people will see that Bitcoin still looks very exclusive because most of them feel they do not have the ability or basic knowledge of technology to own Bitcoin.
If we want to tell people who are still skeptical about Bitcoin, it won't be easy, it will require a process and time and there must be real evidence of what benefits we get so they understand and believe.
I say this because maybe subconsciously all of us here used to be people who didn't really care about Bitcoin before, right?
But in the end, we have our own reasons for trying to enter the cryptocurrency world and trying to get to know and invest in Bitcoin.
I think as time goes by eventually everyone will try to take advantage of Bitcoin, we just need to continue to spread our knowledge about Bitcoin and focus on proving our success in Bitcoin, then naturally other people will be interested.
