Even children in the primary school level know the important of bitcoin and they can explain bitcoin to their parents, despite government is against bitcoin in some countries but people are still learning to improve in the knowledge of bitcoin because when you have the knowledge it can make you to invest in bitcoin to make your funds safe for future use, I don't think people are still doubting bitcoin because they have see the results they want to see before they will believe in bitcoin because it still remain the king among other cryptocurrencies.
I think you are very correct even my little boys at home do no about bitcoin it really so unfortunately to see government play hard to get wey it come to accepting bitcoins..now it so annoying to see why most people follow the government to blaspheme bitcoin…I think the part you say people don’t doubt bitcoin it likely worng because I have a friend till today he has made he choice not to invest or see bitcoin as a means to save up for the future…why do people want to see bigger returns in bitcoin at an early stage before believing in bitcoin should not even be so… people to stop that mentality of such.
It takes experience and wisdom. Neither of which are easily obtained and even less easily recalled.
When I started out as a Bitcoin newbie I would have many of the same thoughts and ideas and even though I had older Bitcoiners tell me where the pitfalls and traps were, I had to stumble upon them myself before I could start understanding and becoming the Bitcoiner I am today.
Everyone has to learn the hard mistakes. But Bitcoin is worth it.
