I have been running a subreddit for a couple of years that specializes in wild economic speculation, not just about cryptocurrencies but in general.
https://www.reddit.com/r/gameofmoney/ Very little is off topic as long as it's not obvious spamming; I don't remove controversial ideas, and indeed post most of my own bearish sentiments there. The focus is supposed to be the link between all "games" and successful n-person game theory applied to the mega game that is the economy.
My own theory is that all 'games' have similar winning solutions and models, and almost everything we experience in life can be abstracted to a game, whether it be the stock market, love, war, or poker.
I enjoy reading the rampant economic speculation here, and would welcome your own thoughts over at my house on occasion. Zerohedge links are especially welcome because doom and gloom is always fun to read.
