Could someone teach me how to do this? I rarely dabble in stuff like this I just lurk on market's and dice games lol.
You have to post your bitcoin address (it can be from blockchain coinbase xapo or from any other bitcoin client), bitcointalk accounts does not have their own bitcoin address. Here is great tutorial from shorena how to sign a bitcoin message: https://bitcointalksearch.org/topic/how-to-sign-a-message-990345
Thanks n691309 I'll take a read of it now and post again after I've read it
I'm not completely sure Xapo can be used to sign messages... I don't have a xapo account (don't really like online wallets), but be sure to try if you can use it to sign a message before you stake a xapo address.
I'd suggest a desktop wallet like core, multibit HD or electrum, but i'm pretty sure you can export your private key from blockchain.info, hence it could be used to sign messages (don't know if you can sign messages from blockchain.info's gui either)
I tested in shorena's tutorial forumjust waiting for someone to verify I did it right lol
