You have just made my day! That is a really rich ETH wallet you found. Thanks for making me laugh. LMAO. You have owned more than a million dollars worth of ETH and another more than a million dollars worth of various tokens, and you are now asking where to start? I doubt you are serious with this.

And if this is really yours, you wouldn't just ask random people here. You would have hired advisers or researchers. Transactions involving more than 2 million dollars are not so small and insignificant that you will just rely on an anonymous forum.
