I have no 'explanation'. There may be was a fork. With low hashpower or asynchronous from zpool ths is possible.
But for me - it is imposible to have 70 millions in 'user wallett' of coin limited to 42 mill.
This is completly bug(or manipulation) on Cryptopia.

I have 15k XDC loss there. My advice is to witdraw anycoin from this exchange as I see other wallets with message 'Coin Fork' there.
If you have coins are in cold wallet - wait , keep ,
I will compile windows version, set additional checkpoints,
That not true that there s only one node - Today I have compiled new wallet - and it is connected to three nodes momentaly.

But the network is not upgraded completly:
xedoscoind getpeerinfo | grep sub
        "subver" : "/Gebo:1.1.2.4/",
        "subver" : "/Gebo:1.1.2.4/",
        "subver" : "/Gebo:1.1.2.1/",

And there is no hashpower. ~ 300kHash only.

I talked with the guy with coin explorer - currently it is reloading with all transactions and may be he will provide rich list to see where are the coins.
after some days.

p.s. I remember one transaction of over 5 millions in one directions around block 983888 folowed by another of over 5 millions - but we will see when the explorer is up.
