Have I been lucky? No.
The bank patiently waited three days before executing the order.
I am afraid they immediately sold the titles and kept the difference. After all no risk here. If the prices would have went up they just would have backdated the sell. I realized why bankers are rich. They have the power and can turn the game to their profit. They just have many possibilities to tweak something such that I lose. </tinfoil>
Ten year later I retried somewhere else, crypto, to realize that the same crowd is also in crypto.
Luckily I didn't go all in. Twice. I can afford the losses.
