it's a good alternative to managing a 2 of 3 multisig yourself. if you're willing to trust them with your transaction details.

Good for KYC stacks and weighing the tradeoffs of having some technical help vs transaction privacy. You can download the wallet onto Sparrow too and have the ability of sending your bitcoin if you have both keys (good redundancy measure in case Unchained ever got compromised)

Buying Bitcoin direct to multisig cold storage is the way to go. Definitely recommend.

Also, I think an underappreciated aspect of multisig with an org like Unchained is inheritance planning. Having a trusted, professional party in the loop who knows what they are doing is extremely valuable.
