Crypto (and more so Solona) has an extreme trade deficit, it's importing way more capital then it's currently exporting (the primary export today is blockspace, I think as DAO's start running SASS services, that will increase the exports). The impact today would be nearly zero. As the deficit evens out, that might change. The local crypto economy is pretty young (it's virtually brand new). As it expands these capital flows will probably change.

I haven't read anything concrete that shows a clear contagion risk, but https://twitter.com/angela_walch is one of the people in the space to follow that is talking about it

Nearly zero.

Probably a nice uptick

Or millions of working people would suddenly be able to afford a gaming GPU and would disappear into imaginary worlds for a couple of weeks.
