Try now. I signed the message with Mycelium. I don't know why after i paste message here and copy from bitcointalk , is failed to verify
Although your address is valid, your signature verification has failed using both Bitcoin.com and BlockExplorer.com
Try again please.
Previously I tried to verify your address using brainwalletx.github.io and it failed.
Now I try it again and it works.
