I just dont understand this GAS thing in my wallet. Yesterday when i trasfered my money to the new wallet i had some gas like 0.0003456 or something. Today i am opening the wallet and this amount is gone, just a button "Claim 0 GAS" When i hit the button it says Sending transaction to your self. What is this all about and why my gas clock is gone since yesterday. Like all gas i earned yesterday is gone. I dont get it how it works. Anybody can exmplain...

Anyway what i can do with that earned gas later? Send it to my ledger wallet for future transactions or change it to NEO coins.? What is this for .....People say is not tradable
