April 13, 2021 Friday was a busy day on the Bitcoin exchange traded fund front as Kryptoin Investment Advisors filed a registration form for a Bitcoin ETF. That means there are now eight such applications before the Securities and Exchange Commission (SEC). The commission also revealed its evaluating WisdomTree’s proposal to introduce a bitcoin ETF – something the issuer has had success with in other markets. “Fast forward to the first quarter of 2021 and the digital assets financial ecosystem, including bitcoin, has progressed significantly,” according to the filing. “The development of a regulated market for digital asset securities has significantly evolved, with market participants having conducted registered public offerings of both digital asset securities and shares in investment vehicles holding bitcoin futures.”
