I believed all these measures embarked by the Chinese biggest bank is geared towards the taking off the much purported digital currency and it trials, all the bans, clampdowns on miners, exchanges etc are taken to discourage the use of cryptocurrencies and the government is trying to enforce the use and adoption of their digital currency, link:

I think so too,,, but we could be wrong because digital yuan already started trialing even in 2020 already and tests before that in 2019. I think the main reason is not to get rid of competition with digital yuan since that is still needed in the economy, but perhaps more to do with energy use in the country. I know China always says it has surplus energy especially with new dams but perhaps they feel they do not want to feed the miners with cheap power anymore? And I bet you it has something to do with miners not properly reporting.
