For the pre sale, is it ok if I send XEM from the exchange wallet? And wallet will be available on pre sale?
(Official response):
Loyalwallet will only be available in early 2018. Meanwhile loyalcoins(LYL) will be distributed through NEM's Nano wallet shortly after the TGE ends on Jan. 10th 2018 or after reaching the hard cap. Whichever comes first.
For sending XEM, specific instructions will become available in the next couple of days.
