Bitcoin posted its longest losing streak in the period since Donald Trump’s US election victory, after a failed run at $100,000 cooled the speculative fervor sparked by the president-elect’s embrace of crypto.

More than $4 billion has streamed into U.S.-listed bitcoin exchange-traded funds since the election. This week, there was a strong debut for options on BlackRock's ETF, with call options - bets on the price going up - more popular than puts.

Bitcoin’s march toward $100,000 gathered pace on Thursday as investors bet a friendlier U.S. regulatory approach to cryptocurrencies under President-elect Donald Trump will unleash a boom era for the asset class. Bitcoin prices topped $98,000 for the first time during European trading, and were last up around 3 percent in midday U.S. trading.
