I feel so sad for Xp holder 
(
(I don't they bought a cheap coin and hoped that the developers would come through, plenty of shitty coins made 100x or more, just not this one it lost 1500% and more, if you bought at the top get out and cry!
the annual staking for xp coin is ideal i think,.not too much and not too little
based on experience long time ago ,dogecoin and reddcoin can soar on price because they accepted on gaming site
