Golden Finance reports that after President Donald Trump did not mention any cryptocurrencies in his inauguration speech on Monday, options listed on the Deribit exchange show that the downward trend in the ETH/BTC ratio continues. According to risk reversal data tracked by Amberdata, as of noon Hong Kong time, Bitcoin call options were trading higher than Ethereum call options in multiple time periods. Risk reversal is calculated by measuring the difference in implied volatility of calls relative to puts, and when this number is positive, it indicates bullish sentiment in the market. Notably, BTC’s risk reversal shows short-term and near-term call options trading 4 to 5 volatility points higher than puts. At the same time, Ethereum call options trade at a relatively low volatility premium relative to puts. In other words, the ETH/BTC ratio is expected to continue its downward trend. Earlier this week, the ETH/BTC ratio had hit a three-year low of 0.03.
