Hello everyone,

Just want to provide more news on the wallet upgrade that we are working to complete. In addition to the litecoin upgrade for faster syncing, we will reverse the staking so that coin supporters will earn a "fair" stake. Coin supporters with huge wallet amounts will stake the least as coin supporters will low wallet amounts will stake more, we choose to do so because of the many complaints that we received over the last few weeks. As far as a maximum coin supply we are going to try something new and bold by not having a maximum coin supply to achieve the goal of XP becoming a utility coin. By making this a reality we seek to gain an edge over competition while maintaining micropayment transactions. We understand the philosophy of rarity, however, if that were truly the case then all coins with a low supply should be high in price and more valuable, however, that isn't the case for every coin. If we every feel that we need to burn coin supply and cap it, then we will do so, until then, it's important that we spread XP all around world and as much as possible. New wallet upgrades should be complete in about a month as this is a huge job which will take some time. We will provide more updates as news becomes available.
