but I need to know how to sign a message when I use an online wallet like blockchain. I paid for the chips with that ewallet, so no way I can just create an offline wallet or connect to this wallet via a client.. suggestions?
and this is final (I hope ) . sorry for sending 3 orders. like I said in PM, I am ordering for a group of people, for a total of > 120+90+80=290 chips.
