My doubt about signing bitcoin sign message.

[letyouearn]

I am using an old address 1BPFKnxAENaxp26g8QbWKUWMuedRo5ZjDY from many years and now in 2015 January  , I got my new Samsung Mobile Phone. So, I have pair my blockchain online wallet with my Samsung Mobile where I installed blockchain android wallet.

From that day , I am always using it on only my phone by setting up a PIN CODE for apps. I didn't access it on my Pc a single time as I can do transactions easily from my android blockchain wallet.

Because of continuous use of Blockchain android wallet on my phone , I have forgot my main password now. But, I can still access above btc address .

So, my question is :

If anyone lost his old and main btc address access . Is that member indicated as a alt of any scammer member or he didn't own that btc address . ?

Now I want to change my regular use btc address. But members here ask for old unedited btc address with a signed message.

I can show and prove in any way that I was using that btc address .

Plz clarify my doubt , what to do with this matter.

i don't sure.
address could not figure out a person.
the blockchain online wallet could be backed up if you have an email address.

How it can be backed up if you don't have a passphrase saved or main password. From the day of using Android wallet , I never think of those and continued using it.

I'm not using android wallets because i question the safety of having my funds in a such mobile wallet, but if you can still use funds from your address, you can
prove ownership by sending a prearranged dust amount to the person you want to prove ownership. Similar to what pp/skrill is using when verifying credit/debit cards.
btw you could also contact blockchain support with your issue https://blockchain.zendesk.com/home

Can I make any announcement or anything that I want to change my personal btc address for receiving funds.

Because members only ask for old btc address signed message only.

And as you said, I can do that but I cannot send small small amount to every person who ask me for signed message. For this issue, I am willing to open a new blockchain wallet and keep the passphrase and everything needed to recover. So that I can sign a mesaage from that new address only forever.

You should have backed up a Mnemonic when you first created your wallet. You can use this to recover your BC.I password.

In theory, your phone should also be storing your password that is decrypted anytime that you enter your PIN on the BC.I app, so you theoretically could get your password from your phone as well, although this would probably require a decent amount of technical know how that the average user probably wouldn't be able to do. 

My understanding is that you are able to send btc "from" a certain address of your choice on the BC.I app, so if you wanted to prove that you controlled a certain private key associated with your account then you could send a small, predetermined amount "from" the address whose private key you claim to have/control.

You should also stop using BC.I as heavily as you do as web wallets are far inferior to other wallet options available as they are much more susceptible to loss and theft.

You should also not reuse addresses as a rule because of the loss of privacy that you incur when you do, along with the loss of privacy of anyone that trades with you (among other reasons)

Ask someone with high trust (e.g. QS, monbux, TBZ, or someone like that) to send you 0.0001BTC to that address, and then send it back to them. If that transaction works out then they can vouch for you and we won't need a signed message.

Can you pm me the Full Procedure step by step how to recover the password from the phone. Also please send me the 0.0001 or 0.0002 btc to my bitcoin address and i will send you back the same to prove the ownership of my bitcoin address. Also vouch for me that I am the only owner of above btc address.

you wouldn't be having a hard time right now if you had asked the loan to be sent to that address, .

As I mentioned, it is only a theory that you can get your password from your phone. It would also most likely involve doing things that are somewhat technically advanced.

Unfortunately, I do not have any funds earmarked for sending micro transactions to other users for the purpose of confirming they control an address they claim to so they can take out a loan that I have no interest in making.

What you want to say ? Be more specific bro. I don't understand what you have said.

I am using an old address 1BPFKnxAENaxp26g8QbWKUWMuedRo5ZjDY from many years and now in 2015 January  , I got my new Samsung Mobile Phone. So, I have pair my blockchain online wallet with my Samsung Mobile where I installed blockchain android wallet.

Plz clarify my doubt , what to do with this matter.

You shouldn't lose any address because you are supposed to backup your private key, don't you?

If you want to change your address, you can sign the following message with your old address:

The (new address) is exclusively controlled by the holder of (old address). Signature by (new address) is equivalent to signature by (old address)

[Blazr]

Is there no way to display the private key on the bc.info mobile app?

I am willing to use mycelium bitcoin wallet and its address as my personal btc address. Also mycelium android wallet has a option to sign a message.

I have a backup of my old address . But I forgot the main password of it. I am still having control over that btc address via blockchain android wallet.

As per your suggestion, I am signing a mesaage you have quoted above and I will save it in my pc or phone.

Is there no way to display the private key on the bc.info mobile app?

I haven't used it but if it works like the blockchain.info site then anytime you want to take backup of your keys you're asked to provide the password of the account and since OP says he forgot his password the app might not let him view the key.

So OP all this time you were sending and receiving BTC from the app, it never occurred to you take a back up of your keys, what would happen if one day you're not able to access the app? How will you take control of your funds then?

I am going to start using mycelium android wallet for my all transactions now. Also I have written the backup words on a paper which will help me to recover my wallet anytime.

It's all about this topic: https://bitcointalk.org/index.php?topic=1153323.msg12157547#msg12157547

If you really are the owner of the mentioned address there should be no problem to send the loan to this address. If you lie tho and the account you're writing with is hacked and you don't own the wallet, sending funds their would be useless for you. In this case you should better offer a good collateral.
