I somewhat agree with a few caveats:

1) it often doesn’t take 3-5 days. Even per their website “Note: It can take up to three business days for Unchained to sign.” I have spoken with multiple folks who had a transaction go through in less than 48 hours. That’s scary. Not having a specified minimum time interval is in and of itself worrisome.

2)For tens or hundreds of Bitcoin bad guys could certainly sit with you for few days, lock you in your basement, kidnap a family member or pet, or even a desperate government could throw you in jail, etc. Important to keep in mind you have to dox yourself to use their product versus other options where you don’t. So your a hacked database away from this being public. Personally I would assume that’s inevitable as that’s just the consistent pattern with KYC data. It’s 100% strictly better than an ETF, but I think it’s problematic how people treat it like it’s impregnable.
