ISN'T a key purpose of cryptocurrencies meant to be anonymity? Does this investigation go against the grain of the platform
no, quiet the opposite, my friend. The big plus about the cryptos are their transparency. The blockchain is meant to be one large script of all transactions that have been ever made. Because everybody can check the script there can be no manipulation of the actual currency. With this method we don't rely on an institution (bank) to manage our money.
At least that is what I understood.
