The approvals of spot bitcoin and ether exchange-traded products and funds (ETPs and ETFs)  in the US were watershed moments for the cryptoeconomy, punctuated by a net inflow of $30.7B since inception (about 11 months). That far exceeds the inflation-adjusted $4.8B that the SPDR Gold Shares ETF (GLD) attracted in its first year after launching in October 2004. According to Bloomberg, this puts these vehicles “among the top 0.1% when it comes to new ETF launches out of the about 5,500 that took place over the past 30 years.”
