Its for everyone but not everyone can be pleased or appreciate Bitcoin as we all are having different opinions, insights, criticisms, etc., about it.
Like my own uncle. Although he acknowledged Bitcoin, but he does not like it. I didnt even convinced him to explore Bitcoin and the crypto world.
One time, his daughter (my cousin) shared to me that she wanted to get in to Bitcoin, but the problem is that she listened to her fathers advice about being against it due to high risks.
But my dad? It took him years (didnt convinced him) until he suddenly talked to me about buying Bitcoin and I educated him about the risks. And you know what? He acknowledged and decided to buy some of his little money to BTC and hold it. I only guided him about the basics of crypto wallets, depositing BTC, etc.
I believe Bitcoin is disponible for everyone, but indeed it's not for everyone, because some people are too closed minded regards innovations and changes (like your uncle), so they are likely to never give up their old ways of doing things to adopt new ones, unless they feel it's extremely necessary.
Good news is that most people aren't freezed in time, so they can always adapt themselves to the environment where they are inserted, just like your father and your cousin did, developing and expressing a legit interest for Bitcoin.
Now it's your task to remove the first bad impressions they had towards Bitcoin through the media and other people in the past.
