staking has never worked for me.
I have been staking 100+ lux for 8+ months in unlocked local wallet. Never have received any pos reward, zero.
Version always up to date to current available, wallet has 16 connections and says staking.
Machine is online 24/7 and pretty much 99% uptime.
100 is too smal quantity to be lucky enough for getting stake. I would suggest to buy/mine more coins to have a POS rewards on stable basis.
As example, here is my recent stakes with 550 coins in "game"
Why are not there new exchanges?
Still in work, nothing to share yet, sorry.
Also check Google Play for android wallet by typing "Luxcore", its there.
Apple wallet still being worked.
