Is the site related to digital currency exchange services not allowed here?

digital currency exchange

To me, both

digital currency = crypto related
exchange = trading

so this may apply

Crypto related allowed?

You asked whether crypto related sites were allowed. The answer to that question is: no, they are not. You then ask whether a specific crypto related site was allowed. If all crypto related sites are banned, that means all crypto related sites are banned. If all crypto related sites are banned, that means every type of crypto related site is banned.
