China Merchants Securities believes that since FTSE A50 has index futures in Singapore, both Bitcoin and A50 index futures have been regarded as mirror assets of the US dollar. When the dollar is weak, the global surplus funds can flow into bitcoin or A50 index futures. At present, the price of bitcoin has exceeded $30,000, suggesting that global funds may continue to flood into A shares. This may also be an important reason for the continuous inflow of funds from the north into A shares.
