It is good to setup ICO company in the land where there is certain type of legistration. That is why some ICO company like to setup in Singapore whereby there is certain laws on ICO but it is not banning on bitcoin or cryptocurrencies. Companies that i know and i can currently recall that is setup in Singapore are Tenx, Enjin and Qtum. There is of course a lot of other places that can setup the company but to target Asia market, it is always better to locate near to asia places.
