Let me explain what I am trying to find.
I download bitcoin client/server, whichever. The very first time it is run a bitcoin address is generated and that is the actual address for that wallet. I can then, through the console or a GUI generate more addresses that refer to the same wallet. They are typically all based on a variant of the original key. Because the wallet is mine, I can search through and there are several ways to find that first address, most very easy.
What I want to do is find the first address for a server/client that is not mine. Specifically, I want to get an idea of the volume of BTC or another coin traded on an exchange. Not a specific exchange, I am going to do this for several and try to get a real idea of the volume of trading that is done in a 24 hours period. I will use YoBit for an example. If I go to my wallet on their site, I can create an address for deposit, I assume that this address refers back to their current hot wallet and it is really an address of theirs that I am using. I deposit BTC there and it shifts into their wallet as part of the hot wallet pool. They use a MySQL database to associate both the bitcoin address they gave me and my transactions with my account. If I deposit a single Bitcoin, it is in their hot wallet and their website database tells the website I have a BTC to play with, withdraw, whatever.
Now, if I take the address they gave me and search the blockchain, I will see the single go in and then take off into cyberspace, as part of their hot wallet. I can watch and track where it goes from there, I can see the address I sent it from originally, but I cannot see any info about the hot wallet and addresses above that address. I can only see the volume that is on one side of my specific address. I want to find the hot wallet master original address. That would show all the volume for the entire wallet. I am not stupid and do not think that one wallet is all they have and all they ever use or used. But, I am trying for a simple 24 trading volume and it is very possible that an exchange will only have that one hot wallet in use during that time period. At least one wallet for exchanges, maybe another for other types of transactions.
So, to summarize, using only a generated address, how do I find the master address for a wallet. I have a small play wallet for gambling, a generated address for it is 1EGQKsjUL4A8GG4tX26dBPFdcRMTDK545R the blockchain shows a small amount in and out for a single transaction I did using that address. Can anyone here get the addresses above that address. I can verify them, if so, how did you do it?
If you are talking about Bitcoin Core, there is no "master address" for a wallet and are not "all based on a variant of the original key."
If you are talking about a different Wallet, you'll have to ask in the subsection for that particular wallet.
There are a number of misconceptions above for Bitcoin Core, btw. ;-)
