According to information provided by CoinShares, Bitcoin investment products experienced a remarkable surge of over $1 billion in funds last week. This brings the total amount of inflows since the beginning of the year to an impressive $14.6 billion. The primary source of this substantial increase in investments can be attributed to the actions of institutions and long-term investors, who have significantly amplified their involvement in spot Bitcoin ETF funds. Specifically, during the week ending on May 24, a staggering $1.01 billion flowed into Bitcoin exchange-traded products.
