David Prinçay, the president of Binance's subsidiary in France, recently stated on May 30th that the introduction of a US-based spot Bitcoin ETF is a breakthrough tool that enables institutions to easily invest in Bitcoin. With the launch of spot Bitcoin ETF, Bitcoin is increasingly being seen as a financial asset for retirement, even by mainstream investors. In the past, only early adopters believed that Bitcoin would be their retirement tool. Now, everyone is considering allocating 1%, 2%, or possibly 5% of their funds into Bitcoin in their 401(k) retirement plans. Some major financial institutions, such as Fidelity, are allowing investors to directly invest in Bitcoin ETF through their 401(k) retirement plans. This development has shifted the perception of Bitcoin from being a speculative investment to a legitimate retirement asset.
