Ok, the desktop wallet is working for claiming the rewards, but how can we STOP BEEING WHALE ?
If I try to STOP I get the "Transaction Incomplete / invalid transtation" popup also.
"There is a bug causing wrong gas values in transactions ("transaction underpriced" errors) on the network.whalecoin.org"
Who can correct this error, and why he didn't do it yet ?
One of devs could fix this. There is a lot of well documented bugs causing "underpriced transaction" in myetherwallet and geth.
You could also try using the desktop wallet to start/stop being a whale.
It should work almost the same way as claiming rewards but you would need to different code in the JSON Interface.
