I saw Andreas's video a few days ago and also thought, "Wow, what a bad idea that will eventually happen." The idea of those investment banks being able to own enough BTC voting power through their ETFs, with the actual investors having no voting power, is the most chilling thought. Them voting on a fork that favors them, or voting down any privacy forks, etc. are real risks.
I personally would never own pretend BTC, where someone else really holds my BTC. It's anathema to the very idea of BTC. But even if you and I wouldn't do it, it's coming.
yes those risks are indeed there so it is good that there will still be the core of people that do believe in the reasons BTC was created. Its good to be part of that
