It seems that a certain BTC whale wants to exchange Bitcoin for USD1, and also wants to get a 20% annualized investment.

Unexpectedly, the liquidity pool for USD1 is too small,

a single order immediately shattered the pool.

The price instantly plunged,

BTC's transaction price slid down to 24,000 USD.

At this point, it's no longer a matter of how much annualized return there is,

even if the investment lasts a lifetime,

it's basically impossible to make up for the loss from this drop.
