Hi guys,

I am trying to find out if I can schedule a Bitcoin transaction for a future date, but still cancel it until that date and if it is possible, how can I do it? I know that in a wallet software I can specify a block, which is fine, but how can I specify it more precisely and which software is the best? A block can vary a lot if it is far in the future. To take the transaction back, from my understanding it is not possible, or can I set it up that I can cancel it for as long as it has not finally been executed?

Thank you for helpful responses!
Chris
