Bitcoin is one of the best investment right now in the world and some people are already going into it however there is still larger number of people who has not started Bitcoin investment and that is why Bitcoin still has a long way to go, the more popular and the more people invest in Bitcoin the more valuable it will become.
Bitcoin price increases when demand exceeds supply and decreases when demand falls this means we can play a part in making Bitcoin more valuable and that part is by preaching about Bitcoin to other people in other for them to invest.
Some people stop Bitcoin investment after some time indulging in it and is because people who told them about Bitcoin didn't give them the right narrative some people will tell them that Bitcoin will give them huge profit in less than no time making them believe Bitcoin is were you can make quick money which is not so, in Bitcoin investment you need to be patient because it takes a long time for Bitcoin to grow.
The more popular and involvement in Bitcoin the more valuable it becomes and we are the factor that can make Bitcoin achieve popularity, someone introduced me into Bitcoin and I believe that was same procedure everyone followed, is either someone told you face to face or someone posted it online and you read about it, this was how Bitcoin became popular and I believe same thing will make it more popular and more valuable than it is now and is part of the factors that can make Bitcoin hit $500k and above.
I don't know if I got this feeling right but IMO you just made BTC look like a big Ponzi scheme in which you got preached to by someone and you want to preach to others, and you saying BTC prices move by demand over supply and when there will be more demand, the price will move up so we need more people investing in it and after long time when enough people already have invested in it we should be making profit then and should get out of it.
It definitely looks like a ponzi scheme to me hahah although it is not. It has some use cases and features it has allowed many to make money from it it's not a small asset now.
BTC is popular because from the very start it gave birth to a new narrative which is digital money not backed by central authorities money means it makes us independent of them and we can invest in it and withdraw money from it too but now most of the people are not converting BTC but they are directly paying via it.
