If BTC Spot ETF is approved, would you put all or some of your retirement portfolio to it?

Institutions look like they're ramping up their efforts to get into crypto before it's too late. With recent news of XRP's win against the SEC, it looks more likely that it will go through. A lot of people have been burnt by the whole Celsius and FTX events and are probably hesitant to use CEXes, but self-custodial does have its caveats with regards to individual human error or the risk of stolen funds through thieves/hackers/family/friends.

I suppose the question is if you were given the same assurances such as FDIC insurance(up to 250k by default in the US) or something similar that your country offers, would you be OK allocating any of your retirement savings to a BTC Spot ETF? How much are you willing to put in? If the funds are also within a tax-advantage account, which means they aren't taxed until withdrawal depending if you have a Roth or traditional IRA/401k here in the US, you can freely sell then re-buy after a month(wash sale trade rule I believe) and not worry about paying the gains on it.

Are you OK knowing that one of the big boys are continually getting bigger and monopolizing on something that was meant to be uncontrolled? Do the benefits and safety outweigh the risk and morality?
