coming from stock market trading and now watching the control (in my case) both coinbase and bittrex have, the first thing I thought of was: the exchanges will be the first targets when the taxmen, er I mean the government want to take over the operation. some combination of bankers/government completely control our current markets, metals, money, futures.
With so few choices available, they could shut down -10- operations and halt cyrpto trading. So Bring on decentralized trading, sooner rather than late.
