Bitcoin futures tumbled Thursday to as low as $58,995, the lowest price since October 2024, bringing its drawdown from last year's high to about 52 percent. The biggest cryptocurrency has been battling with the $60,000 level all year - first in February, where it found support, then again the first two weeks of June, before a pop to over $67,000.Options traders are treating this break like it could be the tip of an iceberg.
