Deutsche Bank — Germany's biggest bank sitting on $1.7 trillion in assets — just flipped the switch on crypto custody services.

This isn't some niche fintech startup testing the waters. This is a systemically important European institution now holding digital assets for clients. The kind of move that changes the conversation from "if" to "when" for other legacy banks.

Three things matter here:

1. Regulatory comfort is real now. For a bank this size to offer custody, they've cleared serious internal risk frameworks and gotten regulatory nods. That's the green light other institutions were waiting for.

2. Client demand is undeniable. Banks don't build infrastructure for fun. Deutsche wouldn't spin up custody ops unless their wealth management and institutional clients were asking for it — repeatedly and loudly.

3. The floodgates logic kicks in. Once one major European bank moves, the others can't afford to sit still. FOMO isn't just for retail — it's institutional strategy. If Deutsche captures crypto-native wealth and the next generation of HNW clients, competitors will scramble to catch up.

This is how $BTC and $ETH move from "alternative asset" to "just another asset class" on private banking platforms. Not through hype cycles, but through boring, buttoned-up custody infrastructure at trillion-dollar banks.
