You just have to look into what markets are the biggest when it comes to ICO's
Russian and Chinese are the big ones, but a good ICO will translate their whitepaper into many languages.
In regards to you getting money out of it, I would ask for ETH or Bitcoin instead of their currency.
Is Chinese still big after the governmental restriction of ICOs in China?
There are already enough solutions to bypass this.. so it might be.. but who knows? It's not like you can really measure it.
