The crash started roughly at 5:59 GMT with Bitcoin falling more than 2% in a couple of minutes while Ethereum followed with a 5% drop. Other cryptocurrencies were also affected, so it seems like it affected the entire crypto market. For example, Solana fell by 7% in just 3 minutes. All of this happened without a clear catalyst though.

In the bigger picture, Bitcoin just dropped into a key level at 111,900 where we got multiple rejections in the past months. This is also where the price is bouncing from as dip-buyers pile back in. A break below this level could take us back to the September low at 107,250 and further below that, the 100K level comes into sight.
