Self-custody cold storage for KAS offers genuine financial sovereignty that traditional banking simply can't match. You actually own your assets—not just account numbers on a bank's ledger. Banks profit by lending out deposits while you earn nothing, and when the next crisis hits, they hide behind "insufficient liquidity" or ATM outages. Your money vanishes into bureaucratic limbo. With on-chain assets in your own wallet, you maintain absolute control. No intermediaries, no failed institutions, no waiting for branches to reopen. That's real savings security.
