英文摘要:
We endorse the idea, suggested in recent literature, that BitCoin prices are influenced by sentiment and confidence about the underlying technology; as a consequence, an excitement about the BitCoin system may propagate to BitCoin prices causing a Bubble effect, the presence of which is documented in several papers about the cryptocurrency. In this paper we develop a bivariate model in continuous time to describe the price dynamics of one BitCoin as well as the behavior of a second factor affecting the price itself, which we name confidence indicator. The two dynamics are possibly correlated and we also take into account a delay between the confidence indicator and its delivered effect on the BitCoin price. Statistical properties of the suggested model are investigated and its arbitrage-free property is shown. Further, based on risk-neutral evaluation, a quasi-closed formula is derived for European style derivatives on the BitCoin. A short numerical application is finally provided.

中文摘要:
我们赞同近期文献中提出的观点,即比特币价格受对底层技术的情绪和信心的影响;因此,对比特币系统的兴奋可能会传播到比特币价格,从而产生泡沫效应,这一现象在几篇关于加密货币的论文中都有记录。在本文中,我们建立了一个连续时间的双变量模型来描述一种比特币的价格动态以及影响价格本身的第二个因素的行为,我们称之为信心指数。这两种动态可能是相关的,我们还考虑了信心指标与其对比特币价格的交付效应之间的延迟。研究了该模型的统计性质,并给出了其无套利性质。此外,基于风险中性评估,推导了比特币上欧式衍生品的准封闭公式。最后给出了一个简短的数值应用。
