4 week reminder - anyone with Nyan at the Cryptopia exchange needs to withdraw it as soon as possible, last date is 10 January. Any NYAN not withdrawn by then will be lost.
If you have a Cryptopia account, check it now - cancel any open sell orders for Nyan, and withdraw any balance as soon as possible.
As of this posting, there is still around 5.5 million on open orders and could be a lot more just sitting in people's accounts.
Withdraws can be to the software wallet, a paper wallet or another exchange.
