It depends on members, whether they will use bitcoin or not. For me, I am going to use bitcoin because it has given me the strong foundation for my future financial improvements. Bitcoin is the completely independent currency where we cannot forcibly suggest people buy it. They need to understand the benefits they are going to get by using bitcoin.
But we should not just depend our financial foundation into one thing. We know that the earnong here is no joke but it is really better to have another work in the real world. We you have work in the real world, all of your crypto earnings is yours and yours alone because you're work in the real world can provide your basic needs and when something happened or the other side failed and vice versa, you have an Alternative work.
We can't force some people to use bitcoin because we have different mindset.. But if they just know how convenient it is to use than fiat and its continues increase in value they will surely like the benefits of it.
We can't force it up to these days, but in the next few years if many people will began using Bitcoin then their kid or the younger generation will use that too without forcing them to use it because it is the mainstream of transactions and they have no choice but to use it like fiat.
