Adam Back, CEO and Co-Founder of Blockstream, identifies pension funds, managed funds, and model portfolios as the anticipated "third wave" of Bitcoin adoption. Speaking in a recent interview, Back contextualized this phase by noting that the first wave consisted of individual investors, while the second was driven by Exchange-Traded Funds (ETFs). He emphasized that institutional integration through traditional asset management structures remains largely forthcoming.

Back highlighted specific preparations underway within the Swiss banking sector to accommodate this shift. He pointed to Blockstream's establishment of an office in Lugano and its expansion into consulting services as evidence of growing institutional interest. According to Back, Swiss banks are actively seeking quantum-safe Bitcoin custody solutions, signaling a move toward more robust security standards for large-scale holdings. The discussion also touched on the regulatory landscape, including Basel rules and their impact on the cost of holding Bitcoin for institutions, as well as the operational choices between building in-house custody versus using third-party custodians.
