To be fair, you are both right here. Coinbase are shady as hell. They partnered with Hacking Team who help authoritarian governments and dictators spy on, monitor, and oppress their citizens. They sell customer data to third parties without knowledge or consent. They listed a bunch of trash altcoins because their owners and investors needed somewhere to dump their bags. They froze markets and insider traded during their launch of BCH support. They track where your bitcoins have come from and where they are going, and will shutdown your account if they don't like how you are spending your own money. I don't trust them whatsoever.
On the other hand, the other exchanges which have been suggested are even worse. YoBit list coins which don't even exist and advertise "InvestBox" products which are entirely designed only to steal BTC from their users. YoBit is an outright scam, and should be avoided by everyone.
