数字货币期权介绍
期权是在未来某个时间可以行使的一种权利。买入期权以后，若到期日行使权利对买方有利，买方将通过行权获得相应收入，卖方需要配合买方行权做出相应支出。若到期日行使权利对买方不利，买方可选择不行权，卖方也无需配合行权做出相应支出。
期权相比合约（交割合约\永续合约）的优势在于，具有“高杠杆”，但无存在爆仓风险，如果亏损则亏损的仅为期权费用，而如果盈利则”收益可观“，因此成为数字货币投资者青睐的投资方式之一。
此外，数字货币期权合约也可以用来进行风险对冲。投资者可以通过购买期权来获得对数字货币价格变动的杠杆收益，同时可以通过出售期权来获得额外收入。对冲交易者可以使用期权合约来保护其数字货币头寸免受价格波动的影响。
