Hi, is it possible to secure your account with a cryptocurrency address Ethereum?
I have a bitcoin wallet only on the exchange.
Technically, it's possible. But, referring to forum rules about Recovering hacked accounts or accounts with lost passwords, admins would accept only signed messages from staked btc addresses:I have a bitcoin wallet only on the exchange.

If you want us to recover a hacked/lost account, you need to prove that you own it. Typically, the only acceptable method of proving ownership is by signing a message (including current date and desired new email address) using a Bitcoin address or PGP key associated with the account. A Bitcoin address or PGP key is associated with the account only if the account posted the key/address, sent it in a PM, or if it is still listed in the account's profile.
In fact, you don't have a wallet yet. Adresses you got from exchanges are just associated to your balance within.
It's not recommended at all to use adresses from exchange platforms because you don't have access to its private key so you don't have the ability to sign messages from; means that the exchange own the wallet and you only have access to adresses.
Here a great thread made by user shorena where you can find a list of secured bitcoin wallets which you have access to the private keys and can sign messages from + guide on how to sign messages for each one: https://bitcointalksearch.org/topic/how-to-sign-a-message-990345
