Right now there is $240,000,000 worth of leveraged longs on just one broker.
Imagine this scenario..
Big bag holders / brokers are loading up just as many short contracts as there is long contracts.
They unload their coins.
Price drops.
Over leveraged longs begin to margin call / liquidate.
Price drops.
Mass liquidation happen and the crypto market tanks again.
They close short contracts, cash in on the $240,000,000.
Buy all their coins back for cheap.
Yep.
