It shouldn't be hard to figure out where the coins are coming from right? Can someone using their lending programs send a tiny amount of BCC from the internal wallet to an external wallet next time they convert interest. Then we can look at the blockchain and see where the source is coming from.
When you withdraw BCC from the site into an external wallet, the BCC coins will come from the site's hot wallet. That's not the interesting part since it obscures the accounting. Exchanges typically operate off-chain - you don't get to see an entry on any blockchain when people exchange one currency for another. It all just happens in a traditional database system.
No. There are just too many shitcoins so we are starting to get collisions in their abbreviations.
