Meanwhile, analyst Yanis said the recent decline was mainly due to aggressive selling by institutional investors on Coinbase rather than a retail panic. He pointed out that global buyers have not been able to absorb the selling pressure, which is hindering Bitcoin's foundation formation. Historically, reversals tend to occur when premiums return to neutral or positive, suggesting continued downside risk at this time.

This repeating weekend pattern has been emerging in recent weeks, with the shaded area on the chart indicating rising premiums and rising prices.

Market outlook and bottom price formation
The continued negative Coinbase premium indicates that Bitcoin has not yet formed a sustainable bottom. Historically, trend reversals have tended to occur after premiums have rebounded, indicating a change in institutional behavior. Until that happens, the rebound could be subdued or quickly reversed by renewed selling from the US.
Market participants are facing a difficult scenario. The current situation is similar to past capitulation phases, but the continued negative premium suggests that the selling has not yet been exhausted. Traders need to determine whether these prices indicate long-term accumulation or just a pause in a longer-term downtrend.
