I reckon should hold both for a while. BTC is good to make money (while it gets adopted more and more its worth more and more-network effect) and comes with risk some which havent been fully seen. The CBs may not fool you but masses will be easily to fool eventually to accept alternatives to real BTC(how with paypal you can buy bitcoin and not really own but have exposure to it or even accepting CBs own crypto) just like they did Gold with paper notes, GLD and other instruments. If that happens bitcoin and you hold that instead of real BTC it will be worth nothing. With Gold(bullion) you can be safe its purpose for me is to protect not earn. Thats why its good to have both positions; a core to protect and one fraction to earn and convert to bullion as time passes.
