according to me the measures taken by the Chinese government are only temporary!
The Chinese president wants to show that he manages everything because the elections are coming soon
Are there any similar former cases where Xi Jinping recalled any decrete before? The damage done is looking rather permanent. Don't know what would be to regain by reopening Yunbi agains (as example)
Worst case scenario, the company will be "sold" off-shore (outside China).
They could easily reopen in Hong Kong.
Two possible SAR regions Macau features enough autonomy, too. That would be the quick fix. On the long term any crypto project that's sitting like a dead duck on one single spot is doomed sooner or later. They will see the money, they will want to grab that money, period.
Either branch out to several different legislation types, or perish.
