We need help of community for addresses identification. I use Binance and Bittrex, so it was easy for me to find Binance addresses, because I’ve withdrew some ADA from it.
As for Bittrex, I tracked down their Redeem Address but still, there should be cold wallet somewhere.
But there are more exchanges, obviously addresses with high amount of transactions belongs to some exchanges and we need your help guys, maybe someone use Upbit, Kraken, Huobi etc. So help is really appreciated.
