Is the encryption index ETF going to da moon?

A WisdomTree executive recently said something interesting: in the coming years, multi-currency ETFs will become the next wave of adoption. What is the core logic behind this? Retail investors can understand BTC, but they get confused when faced with SOL, XRP, and Stellar. Index ETFs are like a "lazy combo" packaged for newcomers in the crypto space, allowing for risk diversification while gaining exposure to the industry.

This year, there has been quite a lot of activity in this market: 21Shares launched a new ETF, and Hashdex recently added mainstream coins like XRP and SOL. The most striking data is that since the launch of the spot BTC ETF in January this year, the net inflow has reached 58.8 billion USD, which shows the enthusiasm of institutions.

Wisdom Tree executives stated bluntly that although the specific timetable is hard to say, index ETFs will eventually become standard, and the logic is straightforward. If this really happens, will it be easier for retail investors to get on board?
