That’s a fair question — and you’re right to ask for the mechanism.
The argument isn’t that redemptions automatically cause Bitcoin to fall, but that they reveal something deeper: liquidity is leaving the system.

Stablecoins like USDT and USDC are the primary transactional layer between fiat and crypto. When their supply contracts sharply, it usually means capital is flowing out of the ecosystem — traders are redeeming for dollars rather than cycling liquidity within the crypto markets.

This matters because:

• Less stablecoin liquidity = thinner order books. That can amplify volatility and reduce the strength of rebounds.
• Institutional outflows from Bitcoin ETFs + stablecoin redemptions suggest a coordinated de-risking — less risk capital chasing crypto assets.
• Historically, periods of stablecoin contraction (like late 2022) have coincided with weaker market momentum and slower recoveries.

So the “peril” isn’t a direct causal trigger, it’s a signal — a reflection of waning confidence and a tightening of liquidity that tends to precede softer conditions for Bitcoin’s price growth.
