Very interesting topic and discussion.. On one extreme is what I call "Warcraft gold" - the in-game gold or currency that we spend without thinking. While I usually use it to buy in-game items, I can use it to buy a monthly subscription and save $15 a month. So it's 99% in-game and not real currency.

Steemit currency and Bitcoin are in the middle. I accumulate, and occasionally spend on real world items. It won't pay my electricity bill, but has the potential to pay for clothes and travel in the future.

I think there will be sharp rises and drops in crypto value. I'm less idealistic - I love real world currency, the "system" has been good to me, and who knows where this will all lead.

This stuff reminds me of the BBS era - the beginnings of something bigger. Like the Bob Dylan lyric, "You know something's happening, but you don't know what it is.."
