Does it occur to you that the freedom many people crave, especially but not only in the developing world, is freedom from poverty?

Only people who are already financially comfortable complain that Bitcoin is about freedom, not wealth.

And in terms of marketing / promoting Bitcoin, yes, people should be told there are no guarantees, so caveat emptor.  But we most certainly should also use the fact that Bitcoin has already made many earlier adopters rich, and could do so again for those who invest now. 

The reason is that people act from self-interest.  SN understood that. It's in everyone's interest for transactions to be processed and the block chain to be secured. But no-one is going to altruistically mine for the common good to their own detriment. So SN implemented transaction fees and block rewards. That way transactions are processed and the block chain is secured, but it happens as a result of miners wanting to become rich(er).

Why do people buy lottery tickets? You've got more chance of being trampled to death by a herd of stampeding wildebeest in the middle of Westminster Abbey than of winning millions on any national/state lottery (well, almost). But people buy those tickets anyway because they want to become rich.

Bitcoin is an investment opportunity that offers a much greater chance (though not a guarantee) of becoming rich if you invest now.

Promoting Bitcoin in a way that appeals to people's self-interest could well encourage wider adoption in my view.

When people recognise that Bitcoin could make them a lot of money when it goes mainstream and they buy some bitcoins as a result, they then have a vested interest in seeing Bitcoin succeed.

When the number of people with a vested interest in seeing Bitcoin go mainstream reaches a critical point, then major businesses will all start lining up to take payment by Bitcoin, because they want the custom of all those bitcoiners.

Bitcoin has already made earlier adopters rich. It could still make others rich if they invest now. People act from self-interest, so if we want Bitcoin to succeed we should appeal to their self-interest.
