If you think I'm being out of line, the solution to this with the assistance of Bittrex would be like so.
1)Hey Bittrex; how many coins do you guys hold?
Bittrex XX,XXX
Okay, please update new codebase/wallet/provide new wallet address
Bittrex: Updated, heres addresss
Great, here are the new coins
Just take a snapshot at a given blockheight, and premine the new coins to the addresses that have funds. It takes no manual work at all on either your part or the coin holders.
And that is how it's done, dev - simple and clean. No need for sending wallet.dat files anywhere.
PS: Ensure that the current COV1 public/private key combos are still valid for COV2 when doing that. Also take care of trading to be halted on exchanges prior to taking the snapshot for the premine of COV2 (for obvious reasons).
@ bittrex/riechiela: As for the coins still deposited @ bittrex: So the COV addresses currently associated to bittrex accounts will also be associated for COV2 when taking this approach, right?
