I appreciate your work, but we've been hearing this same mantra for the last 2-3 years.
First, Chinese stock markets are completely different from western stock markets, meaning they are not viewed as a long-term store of value, they are treated more like gambling. And they are dominated by a few quasi commie gov't owned and controlled companies.

Don't get me wrong, I'm not a perma bull on the US stock markts, but market participation rates are still low. People in the US are still historically under-allocated to stocks as their trust hasn't been repaired from the 2008-2009 financial crisis.

And when you say "stock markets" are propped up, you really only mean the US markets, and when you examine further, you mean a few stocks. There is no breadth or volatility. And just because we are at historical lows (volatility), doesn't mean it can't continue for some time. Things don't always immediately revert to the norm. After all, a high water mark (or low water mark) isn't forever.

And your audience on a beta social media based on blockchain will certainly draw people that are skeptical of the broader economy. I've lived around the world, and as bad as things are in the USA economically, it is far worse almost everywhere else. Who wants to and can move to Greece to open a tech start up? Nobody, sorry Greece. They want to go to California.

And the last point I'll make, what is the alternative? TINA, remember that? All that money going to flow into government bonds? Don't think so.
Anyway, keep posting, nothing like healthy debate to make a market! Peace out.
