how do i change the btc address linked to an existing byteball address i used in the 2nd distribution? my coins have moved to a new address i would rather just sign a message when participating in the 3rd round.
You can't change a linked address, but you can add a new Bitcoin one linked to the same Byteball address. To link a specific Byteball address to a specific Bitcoin address, chat with the bot, enter your BB address, then your BTC address, the bot will wait for the signature, once you enter it, it should be okay. Chat with the bot again to see if it lists your new links and verify it on
