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.
