18 to 35 years invested most in bitcoin. So, they will be the ones that can easily be convinced to invest in bitcoin. Then followed by the people within the age of 36 to 45. As the age increases, the probability of investing in bitcoin decreases. Older age invest less in bitcoin. This is according to some researches.

For the time being, my pick would be 35 and under.  And yes, the younger, the more likely to convince.

Old people and technology rarely ever fit together.  It is almost impossible for a lot of the elderly to be convinced that there are OTHER ways to do things as well.  Most of them want what is 'real' as in physical assets, but even then I doubt the majority of them are investors anyway.

I will also choose the two age brackets which is between 13 – 30. They are the wide range of individuals that can easily be convinced onlike the older ones whom might have tried several investments thereby becoming more careful and little bit more skeptical about going into new investments especially since they haven't tried it before. Although if I may also mention, I can say that it also depends on the individual involved. Some individuals might be a little bit easier to convinced if you come up with data (however little) to back up your claims, while other might never pick interest at all since investing in bitcoin is like investing in the thin air.

Gen Z and younger Millennials (18-34) are more likely to jump into Bitcoin. They’re digital natives, drawn to innovative finance, and less fazed by volatility. Older folks usually lean toward caution with unfamiliar investments like crypto.

I'm picking these 2 and I have my own reason why.

Young Adults (21–30 years) - at this stage, the person already is finding ways to make money since most probably the person already graduated from college already and finding a job. With how Bitcoin is being promoted right now which is a way to make money (which is completely wrong, but there's nothing that I can do about it), the person will be easy to convinced since he's finding a way to make money, and for him, it's like Bitcoin is the solution. With that, they'll invest into Bitcoin. Of course, not all in this age group are that easily to convinced still.

Senior Citizens (46 years and on) - I remember a community here in our country where they're attracting senior citizen and old people to invest in their project and join their community. BTW, this community promotes PI NETWORK, a very skeptical project, but these old people aren't equipped with enough financial literacy hence, these predators are taking advantage of them. I know it's a different project, but I took them as an example and because of that, I realized that it's easy for them to get convinced since whenever they see that they can make money by investing into it, they'll jump no matter what.

The young and middle aged people are most interested in and most actually invested in Bitcoin. There are some reports on Bitcoin demographics. The demographic changes with time as human generations roll over and the young replace the elderly over years. It's very basic and traditional trend in all societies when wealth distribution naturally moves from the elderly and middle aged people to the young but time flies fast and the young in 2025 will become middle-aged next 20 years and kid nowdays will become main backbones of Bitcoin adoption next 10 or 20 years.

This signals very bright future for Bitcoin adoption, its value and also price because demands will increase very sharply with time.

I will pick these two set of age range people as the ones that can confidently embrace bitcoin adoption and invest into bitcoin because they are open to new innovation. We might say that 40-45 years is old but they still have the youth blood in them and most of them are still investing for their old age.

The first person that gave me a little insight about bitcoin was 42 years old three years back and he is still hodling his bitcoin investment till date. Only the elderly will find it difficult to accept new technology based on their old way of living and believe that they were in the world before us and know better than we the youths.

There's no one in this world want to put much effort to earn, including 90 years old grandpa.

What you said is like a gambling mentality, gambling are popular in any ages.

It requires two criteria.
1. It's generating coins (money) without capital and easy.
2. People who close with them are participating too.

That's why, airdrop and bounties are very popular for Average Joe because it doesn't require capital to get.

It will obviously be those under the group of adolescence between 13 and 20. The older the person is, the more fixed his opinions would be and the harder it will be to convince him or change his opinion. But younger people I would say are a lot more open minded. Parents must think that their teenagers are the most stubborn but actually it is the elderly that are the most stubborn and won't change their beliefs once they have committed to it.

By the way, aren't senior citizens like 60yo? or does just that apply on my country?
