Regarding the coins transfer from the old to new wallet.
Can someone confirm where these new coins have come from?
I assume from a premined account but where can we verify the balance of this account?
Yes, we premined the new chain in order to allocate coins for the refunds, bounties, exchange fees, etc. 456,000 coins were allocated to cover all the possible previous coin holdings. Any remaining funds for coins not claimed will be allocated for bounties.
The refund wallet transfer was split into multiple transactions, but
