You have misunderstood bitcoin. Likewise, there's no such as marketing for bitcoin. There's no central authority that provides marketing or any plans that they have to be executed to make it popular. It just grew naturally for a decade until it got on the mainstream.

What bill is that?

What's smart is that to own at least a single bitcoin if you can. But if you can't, then keep accumulating until you're hitting near to it or at least one or two decimals for bitcoin.
