Bitcoin (BTC) miners' first-quarter results may disappoint because the hashprice, a measure of daily mining profitability, fell further and trade tariffs weighed on the market, asset manager CoinShares (CS) said in a blog post on Friday. "Q2 results may show deterioration, as tariffs on imported mining rigs range from 24% (Malaysia) to 54% (China)," analysts led by James Butterfill wrote. Bitcoin miners that are dependent on older or less-efficient rigs are faced with higher exposure to these tariffs, the report said.
