Do I need to send multiple transactions of 1000 coins to one second address, or do i need to create a separate addresses for each tousand?
Kinda confused

either would do the job but hammz said optimal (optional i guess was a typo) input 1000
whether that means over 1000 is ok is another matter depending where the bug kicks in so you might be better off doing chunks of under 1000 like 950 or something
