If we are only in for diversifying inside crypto, we can already do that before, because there are still lots of cryptos apart from Bitcoin but these ETF's are only great for the traditional investors who doesn't like being decentralized. Indeed that this gives them more choice or a chance to now have a diverse ETF crypto portfolio. ETH can have an indirect positive effect once this event happens, so it's a good idea to also invest in ETH.
It is also much safer because even if other collapse, ETH can still carry on. I can proudly say that cryptos are already in a global adoption. We can just take a look around us to see it but these new developments here are only an addition to make things more polished.
ETFs are the perfect way for the wealthy to invest in Bitcoin without the need to know how to use it. The responsibility of securing, storing, and managing coins is left in the hands of a custodian. The more BTC is accumulated by institutions, the more concentrated its supply will be. This will lead to centralization issues in the long run. But I wouldn't worry about this, especially when a sizeable portion of the circulating supply is still in the hands of the people (self-custody).
The success of BTC spot ETFs has led to the creation of ETH spot ETFs. If this last one becomes a huge success as well, we'll be seeing ETFs for other coins such as Solana and Litecoin. "Hodlers" will benefit from such ETFs as they increase market demand and mainstream adoption. I feel this is just the beginning of a long journey for widespread adoption of crypto. Hang on tight as this is going to be a wild ride.
