I have sent messages to BITTREX and BTER asking them to update their wallets - if you are waiting for a deposit or withdrawal to confirm with them then once they are updated things should get back to normal.
Currently I am taking the generous view that the slow network is the reason why the "donation wallet" is still empty, no doubt plenty of you SPARK owners have sent donations but the txes are still waiting to be confirmed ;0
I honestly have less than 2k SPARK, I do this mainly because I find it interesting but updating and compiling a new wallet release is a time consuming process so motivation is important! Moral support is most appreciated but financial rewards are also very encouraging so feel free to show your support by sending some SPARK to Sg2dujC3jMa9j1ff41sjAZRV4mZkjwgN6G
Thanks!
