1. You do not have to move all funds through fireblocks wallet (vault) and send directly from partner exchanges to the hot wallets maintained by any exchange. Wallet solutions are scalable, outsourced, and upgraded by Fireblocks. 2. A layered security that requires signatures from multiple parties by setting rules through APIs if required. 3. Decent support that fixes issues if there is any problem. 4. Feels complete control over the funds.
