Am I the only one doubting the OP post, Everybody have been asking how he lost the money but he is not saying anything, I don't believe his story because he should have shared more information on how he lost the bitcon, at least it will have helped other members of the forum but he is not saying anything, the story might be true, but since the OP can provide detailed information on how he lost the bitcoin then its suspicious and the story might not also be true.
Maybe just a fictional story or I don't know, because there is no further clarity about the OP's story.
Losing 10BTC in the crypto market certainly doesn't make sense if he only trades on the Spot.
But if he trades in Futures Mode it will definitely happen. anything will be lost in an instant if you can't trade futures.
10BTC is a large number and the OP is also not clear on the chronology, maybe he just wants to enliven the forum with random posts made.
