To tell you the truth, I personally am more skeptical that this ETF will give as much to Bitcoin as it did to gold. Gold is hard to buy, hard to sell, each transaction carries the risk of fraud (fake gold), requires a physical transfer to the mint/store and has a huge spread. Gold ETF solved all these problems and made it possible for you to buy physical gold in 2 clicks from home. The same cannot be said for bitcoin, because bitcoin is like gold with build in ETF. It's easy to buy, easy to sell, divisible to cents. And it's not like the ETF will open doors to big institutions either. Microstrategy didn't need an ETF to buy nearly 1% of all bitcoins.
buying and holding bitcoins requires a specific knowledge that an "average joe" has difficulty to understand. For what I have seen, even a person with more experience or informatic culture must spend some time before being able to mastering this argument.
Gold is just... a "shining rock".
You take it in the form of a coin/bar/stone and you are done with the purchase storage part.
With bitcoin, if you think about it, it's not the same thing. And above all, there are now a few places (very often with insane high spreads) that allow you to buy it "live" in an easy way.
any other financial product you can buy/store it easily.
with bitcoin this is currently not real!
