I watched some YouTube bloggers who tell guides how to find successful whale wallets in DEX, and poke their deals. Such whales have insider information. But when I really started checking the transactions of the token wallet, I saw that most of the first buyers use clean and new wallets. It's logical, why leave the story behind, so that people like me and other guys copy them. I thought that it would be possible to track the crypto wallets that have just been created, and monitor them. parse wallets from the first tranazktsii, map their addresses with the names of tokens and try to repeat their purchases. Maybe my questions are stupid and my ideas are naive.
I use both Nansen and Arkham Intelligence for wallet tracking. Don't expect every feature to be free, though.
Speaking of Nansen though, I'm not really sure if you are aware of this,
[Warning]: Crypto firm Nansen ask users to reset their password.
Also, you really can't know if a wallet has just been newly created. You can only know by their first transaction. And how do you even know for sure if the new wallet is a whale's wallet? It could be anyone's wallet.
That's why I don't trust those accounts that says they follow whales wallet. Sometimes it just create more confusion for newbies.
As for the service ask by the OP, there is none so far and I think it's better be that way though.
