这说明，占全球主体（53%，超过半数）的国家仍在观望以比特币为首的数字货币在境内的合法性，也代表了比特币的“黑天鹅风险”依旧很大，因为其中一部分国家最终可能会作出限制数字货币的立法决定。
This shows that countries that account for the global majority (53%, more than half) are still indecisive about the legitimacy of digital currencies represented by Bitcoin. This means that the “black swan risk” is still very large for Bitcoin, because some of these countries may ultimately make legislation that restrict the use of digital currencies.
