Very impressive to be 15 years old and designing great apps like this. Definitely a good concept as well, predicting market movements based n the actions of whales is a great idea. Would be nice if it already came with a pre-defined list of the top 100 EThereum wallets by size. Eventually I can imagine people selling custom lists for this, e.g. a known high profile trader list, hedgefund list, ICO list etc.
Oh, its a really great idea. Definitely, need to add this into the app.
Do you have any useful links for this? I know only
https://etherscan.io/accounts but a lot of them are just exchangers wallets.
