How will the ban of all ICO in China affect the market of cryptocurrency?
It's already affecting it. China has huge population and if 1% of that population get in to crypto, it will increase the overall capitalization and steer development. Adoption will also be faster since crypto is more about people's freedom from centralized system.
You have not understood a question i think. Monsterdoge asked "HOW will it affect", not "will the ban affect".
