BitMEX co-founder Arthur Hayes has today reinstated his bullish stance, posting several optimistic tweets on social media. Although the Bank of Japan raised interest rates by 0.25% as expected today, it expressed a dovish policy stance in its statement, clearly indicating that "real interest rates are expected to remain significantly negative," and that the accommodative financial environment will continue to support economic activity.
