It is right now and has been for the past 2 years.
Until the ETF kicks off and/or a massive adoption event by either banks or people, bitcoin is laughably illiquid. On orderbooks today, there is probably 50k BTC buyable up to 100% of its current price. You could literally clear the entire world's order book for 1 hour with little coordinated effort for 30-40m USD. Conversely, because of sites that allow leverage and futures, consider how little BTC or USD you would need to begin pushing the price around. Someone with as little as 1m USD or BTC equiv could push BTC's price +/- 5% during off hours with literally zero effort or sophistication involved.
fake a few screenshots about OK coin, throw it on reddit. have a few sock accounts "confirm"
start dumping 1-3k btc on finex and finish off on btc-e. buy on the way back up
something so stupid and simple as that could cause a +/- 10% swing at current prices TODAY.
