Bitcoin's recovery to above $63,500 from $58,500 over the past two weeks raises questions about its sustainability. My on-chain data analysis points to a troubling structural imbalance: the current rally is driven solely by aggressive use of offshore leverage, not by real spot demand from US institutions.
The main indicator of this divergence is the sharp contrast between the dynamics of funding rates on Binance and the Coinbase premium index. Over this period, funding rates on Binance surged by 860% relative to the 90-day baseline, signaling aggressive long position opening in derivatives. At the same time, the Coinbase premium, which reflects spot demand from large holders and institutions in the US, has consistently remained in negative territory, fluctuating between -0.09 and -0.17.
What does this divergence mean?
This situation is a classic signal that the price movement is speculative in nature. The US spot market, where institutional capital is traditionally concentrated, is not participating in the rally. The rise is supported exclusively by the global, offshore, and retail derivatives market. Additional confirmation comes from the NVT Golden Cross indicator, which has sharply declined by 579% relative to the 90-day baseline. This means that the value of network transactions is growing significantly slower than market capitalization: the price is detaching from the network's actual utility.
In simple terms: the Bitcoin network itself remains relatively calm, while activity in derivatives is accelerating. This highlights the disconnect between market price and the ecosystem's actual value.
What risks does this pose to the market?
The structure of the current rally creates an extremely vulnerable configuration. Historically, such divergences have preceded local corrections. For me, the key signal will be the dynamics of the Coinbase premium. Until it moves into zero or positive territory, confirming the return of spot demand, the market will remain fragile.
Overloaded long positions on offshore exchanges become fuel for a potential leverage flush. A sudden liquidation of these positions could trigger a sharp decline.
My conclusion: The current Bitcoin rally is not organic accumulation but a speculative game. It is held up by leverage that could be unwound at any moment. Further sustainability will depend entirely on whether real demand from the US returns. Until then, the advantage remains with speculative capital, not fundamental accumulation. The market is in a high-risk zone.
