Bought 200,000, the total cost is around 4U, one sold for 79, one sold for 51.

The one sold for 79 had its slippage changed to 50% immediately, the second one had its slippage changed to 50% after the price dropped and was executed.

Lesson learned: as soon as you get the coin, change the slippage to 50% before it goes live; the automatic slippage of 15% often can't execute, and wasting time with that a few times has resulted in lower prices.

When the price drops, don't rush to sell to avoid executing at the lowest price; waiting for a rebound can still allow you to sell at 64.
