Large Bitcoin ETF Grayscale Bitcoin Trust (GBTC) has registered an influx of new investment, its first since its launch in January, Farside Investors reports.

On Friday, $63 million was added.

GBTC, despite its high fees, has long remained the main investment vehicle for investors looking to invest in Bitcoin. However, it faced competition in January when it converted to a more easily traded ETF and nine competing Bitcoin ETFs began trading.

However, BlackRock's iShares Bitcoin Trust (IBIT) is challenging GBTC for the title of the largest Bitcoin ETF. GBTC now has $18.1 billion in assets, versus IBIT's $16.9 billion.
