We don't know whether 50K is sufficient to be listed on Kraken. There is no official info, somebody just posted this in the forum. Perhaps NEMs trading volumes are too low for Kraken to list it.
You could be right... Perhaps this needs to be done systematically, make people aware of coin, get the volumes up and then approach to the biggest, in that case they should gladly accept it. According to all that I've seen so far, this is not a small time coin.
Either way, I'm down for whatever...
