The total cryptocurrency market capitalization had repeatedly taken support close to the $250 billion mark since mid-July of this year. However, the recent collapse in crypto markets led by Bitcoin (BTC) has broken the support and market capitalization has dipped to just under $220 billion.
It is difficult to pinpoint the exact reason that started the fall. A few speculators might have built up positions expecting the prices to surge following the launch of Bakkt. However, when that did not play out, they started closing their trades in a hurry. As a result, important support levels cracked and the rest of the traders were forced to close their long positions.
