I lost this address a couple of weeks ago after I uninstalled the wallet and not being able to recover it since the paper I wrote the seed phrase of it was in a bunch of messy old papers and I disposed of.. This is my new address and signing
Can you sign a message from any of addresses you have used before?
Staking a new address without proving your ownership over the address you have staked before defeats the purpose of staking a bitcoin address.
You can use
ninjastic.space to see the addresses you have used before.
I might be able to prove ownership of certain addresses I used in past which are of exchange's addresses. Haven't really used many personal wallets and disposed of any which was empty in terms of any money for months due to non participation in bounties and taking a break.
