Bitcoin has broken through $71,000, and some people have begun to predict the future of Bitcoin. In fact, for these predictions, BitMEX founder predicts: US-Japan currency swap may trigger a surge in cryptocurrencies, and Bitcoin is expected to hit $1 million. Arthur Hayes, founder of BitMEX, pointed out in his latest article that in order to curb the depreciation of the yen, the Federal Reserve may reach an unlimited dollar-yen swap agreement with the Bank of Japan. Hayes believes that this move is equivalent to the Federal Reserve implementing yield curve control, which will cause a sharp depreciation of the US dollar. The depreciation of the US dollar means a sharp increase in global US dollar liquidity. This will be good for the cryptocurrency market led by Bitcoin. If the US and Japanese central banks really adopt a "simple and crude" currency swap policy, it will trigger a new round of cryptocurrency price increases. At that time, the price of Bitcoin is expected to hit the $1 million mark, or even set a record high. Hayes recommends that cryptocurrency traders pay close attention to the future changes in the US dollar-yen exchange rate, and at the same time, they can appropriately increase their cryptocurrency allocation. Once the market finds that the US and Japan are conducting large-scale currency swaps and the scale of swaps continues to expand, it is likely to mean that a cryptocurrency bull market is coming.
