This is why I like helping people: you learn something new when you do. For example before I got my Trezor hardware deterministic wallet I used blockchain.info extensively. I had not bothered to look at their new wallet because I now believe that everyone should use deterministic wallets for many reasons (see my post history on this subject).
Behold the new blockchain.info wallet
is a deterministic wallet! That is fantastic. I can now just send noobs to Blockchain.info, have them use the new wallet and wala, they are using a deterministic wallet. Happy day.
Knowing this let's get on with your problem. Do the following and carefully answer
all of the following questions:
Did you create a brand new wallet for this transaction (pressed Create New Blockchain Wallet) or did you use the same wallet you had used before for this transaction (pressed Login To The New Blockchain Wallet and logged into a wallet you had previously used)?
If you used the same wallet had you used the wallet once before or a few times before?
You said you had bought BTC before, right? This is not your first purchase, right?
If you bought BTC before did you create a brand new wallet at blockchain.info every time you bought BTC?
You said you are using the New Blockchain Wallet. That means to get to your wallet now you are going to this page:
https://blockchain.info/wallet/#/and clicking on "
Login To The New Blockchain Wallet". Is that right?
1) Log in to the wallet
In the upper right hand corner is the balance shown 0 BTC or some other number that is not zero?
2) Click on SETTINGS
3) In the drop down click on Addresses
4) You should see "My Bitcoin Wallet (N BTC) / Default Show xPub Manage Addresses" Where N is a number of Bitcoins.
Is that true? Is that what you see?
Is the value N equal to zero or is it another number?
5) Click on "Manage Addresses"
Are there any addresses showing up on the "Manage Addresses" page at all?
If there are addresses how many addresses are shown?
If there are addresses is the address 1Masr1mezkmAqhtWT9RsWzt2e21aYApco showing up in the list?
This is very important. Read this very carefully, do exactly as I say, and report back exactly what happens:
If there are no addresses at all
OR if there are addresses but the address 1Masr1mezkmAqhtWT9RsWzt2e21aYApco is not in the list then press the New Address button ONE TIME.
Now you should have one address if there were none, or a new address added to the list if there were already addresses there.
Is the address 1Masr1mezkmAqhtWT9RsWzt2e21aYApco now in the list?
Do everything I asked and report back and we will take it from there.
