I got an email today from no-reply@cryptopia.co.nz to my old email as used at cryptopia, before that exchange folded a few years back.

What it says includes

"Dear Cryptopia Account Holder,

We invite you to begin the Cryptopia Limited (In Liquidation) account holder claims process.

Registering on the Claims Portal is necessary to enable you to lodge your claim.

Failure to participate in this process may mean we will be unable to
return your Cryptocurrency. "

Are these real ?  If so then everyone else with a cryptopia altcoin trading account should get one too, and somebody will post here a report of getting back some of their old altcoins.  If not then I have no reason to disclose anything to the entity who now have the list of user emails.

I was considering buying a shiny new 12V 1600W power supply to replace an old one with a second hand miner but I'm seeing conflicting figures.

Mains electricity Voltage here at 50Hz was 244 Volts rms typical last time I checked and formally could go up to 253 Volts in this region.
Bitmain advertise their APW3 power supplies for 220 Volts and up to a maximum of 240 Volts.  As in "it might break" if it functions as advertised.

I read elsewhere online that they are good with British mains and rated up to 264 Volts.  I do not make sensible purchasing decisions on a single source of internet gossip.  What works in the UK ?

I just got a useless reply from Bitmain support "Please send us the Order ID and a picture of the SN tag. "
