I think you don't understand the situation here (somehow). This thread was made for bitcointalk members to prove ownership of their accounts in the case of someone account gets stolen or hacked or lost; so he can simply make a new alt-account and sign the address posted here by his original account to have irrefutable proof that he is the real owner.
That you are a newbie user, i don't see the reason why your first post contain your btc address. Unless you are an old member of the forum willing to restart again with new account (hope your previous account didn't got autobanned cauz you are not allowed to create another one), you have a long journey of learning before thinking to stake your btc address.
If you are sure of what you do, make sure that you can sign a message from the address you post.
