Compass Mining is now requiring signed attestation of residence for users who host a miner on one of their Canadian facilities. On behalf of the Canadian IRS.

While non-Canadian residents are pretty much still(?) fine, as they only have to attest they are not residing in Canada, this is likely only the first step.

Assume that in the non too distant future you will have to fully KYC for hosting mining equipment.

I would normally do some snarly comment, like "get your miners off the exchanges", but that's easier said than done.
