when will they release the polo and cryptopia wallets
Good question, not sure what their criteria is. But chain is working reliably under the current protocol and most nodes are in the v0.9.7.x series, as they should be at this time.
But, there are a few v0.9.8.3 nodes still appearing, and in fact someone mined a few blocks beyond height 518191 (iirc, like 20 blocks or so) on that fork, which I found odd. No one should be running a v0.9.8.3 node or wallet. I have taken down the Release binaries for that version, (because there were last minute questions about it right before the forkheight); but it's possible that a few are out there.
Please make sure that your nodes and wallets are on the Bitmark v0.9.7.x series.
This is the correct version to be on at this time.
There are also a couple of nodes listed on the Chainz explorer as v0.9.5 and one as v0.9.2.2.
Those version are old and totally obsolete.
¿ Maybe an old VM running somewhere, forgotten.... Or just ...
¿ A monitor to see if anyone mines that old fork ?
v0.9.5 had a SCrypt diff in the 20,000 IIRC
