for this problem i will answer slowly.
the reason i changed the password for this account was because all the data such as the emails i saved on my laptop were lost. my laptop was broken a few months ago, i can't use it anymore
and for the btc wallet problem i only store the address on the flash disk and some login ids. but my btc blockchain login password is missing along with other data. because i save the id and password separately.
First, I'm glad you came here to explain my concern about your account being hacked, sold, or changing hands. Then, you can convince me in any way as long as the reasons and evidence you have are reasonable and valid as proof that you are still the original owner.
About your reasons saying that your laptop broke in the last few months so you have to change your account password and loss of access to the wallet until you can't sign messages, seems to be common reasons that are often used by new users from accounts being sold, hacked or changed hands. That's a weak enough reason to convince people to believe that you're still the primary owner of the account. Then your posting pattern seems to have completely changed even though you could tell that you are also a poster who likes to post on gambling boards.
but i still have data on the wallet erc20 0xcdD493d4f50c1997649A2c77d296d3C6506ac40D which i used to join the bounty last year.
is there any other solution besides using btc wallet signature? or i can use the erc20 wallet and send something to prove this is indeed my account. i just lost some of my data that was on the laptop
You say your laptop is broken and all the data stored on the flashdisk has been lost, then how can you still save the actual ERC20 address you used in the same year as this bitcoin address
19a7UVCra8iTPs3X8jPxw6PoTyG9nNC2x and it's only a few months apart? Now, I don't think your logic is correct because if all your data is lost then you should also no longer have access to that ERC20 address. What if you work with an account seller and you ask him to send some shitcoins from that address as proof that the account is yours?
i don't deceive anyone on this forum and i don't make spam shit post. so no need to accuse me with your suspicions
Before you change the password of this account, I can absolutely prove that you are a poster who usually posts one line. But after changing your password your posting pattern has changed so it is natural for me to suspect that you are no longer the primary owner of the account regardless of whether it was hacked, sold, or changed hands.
So if you want to prove that you are the main owner of this account especially after you have been inactive for a long time and changed the account password then prove it by sign message or something reasonable.
