It was said Bittrex and Poloniex will distribute Ardor to exchange NXT holders. How is that possible? Will they also take snapshots of exchange accounts every hour?
i seems safer to just withdraw and do it on your own computer. i dont see how the exchanges are going to split the ardr tokens as its given out by averaging how much you have over X amount of days. this means the exchanges would have to write up their own script just to calculate this for you, i doubt they would do that.
This is exactly what these exchanges did and do.
Some exchanges are happy to go the extra mile for their users and with our help they are calculating this.

Still: the most exact way is always from your own personal wallet.
