Inflows into Bitcoin and crypto exchange-traded products (ETPs) have now risen for 9 straight weeks, according to digital asset manager CoinShares.

Bitcoin ETPs saw $312 million of fresh inflows for the week ending November 24th, propelling  year-to-date inflows to around $1.5 billion. Total crypto product inflows hit $346 million last week, extending a hot streak since late September.

Before September 25th, crypto funds experienced persistent outflows amid market doldrums. But sentiment has shifted thanks to building optimism that U.S. regulators may finally approve a spot Bitcoin ETF product.

Last week's $312 million Bitcoin haul marked the largest single week of inflows over the 9 week surge. CoinShares reported Canada and Germany led inflows, while surprisingly U.S. activity was muted at just $30 million.

With sentiment and prices lifting, crypto investment products now tally $45.4 billion in assets under management - an 18 month high. CoinShares speculates the prospect of an SEC-approved U.S. spot Bitcoin ETF is fueling the capital rotation into the crypto space.
