I'm trying to get in on some ICO's, and was wondering what the best way to get in was using Parity. I've read some people say that you should use n-2 so the block number the ICO starts at minus two blocks to ensure you get in right at the block start.
But I've also read this doesn't work anymore. I've read to put n-1, 1 block less as well. Can someone who has knowledge in this tell me what the best block to send at is to ensure I'm one of the first one's at the starting block?
