Unified Trading Accounts: A big deal for Derivative Traders?

So I've been seeing some exchanges talking about unified trading accounts. What's the deal with that? From what I gather, this setup lets users trade Bitcoin and altcoins while also opening positions in stablecoins like USDT or USDC without the hassle of moving funds around. Seems like a solid idea, right? But I'm curious, is this really gonna improve our trading experience or just another gimmick? I mean, how does it actually work with margin trading? Anyone here using it? Share your thoughts!
