Just to put in in perspective:
Kroor said to the user dennmarko that he would return 110% if dennmarko would send him btc. And so he did.
Kroor said as well that if he'd lose, he'd pay it from his own btc.
Kroor did (unfortunately for dennmarko) lose.
What happened next is that Kroor said to dennmarko that he needed to confirm in the chat that he got his coins, while Kroor actually didn't send, so that others would think that kroor actually returned the money (which he didn't).
By doing that, he hoped that others would trust him as well, so that he could get others money.
All in all: kroor didn't return dennmarko's money, which he promised to do. After that, he wants dennmarko to lie in order to scam even more others.
So that is the reason explained clearly not in anger like the op lol From hearing that op i would say you deserve to be banned/blocked why deceive and lie to people then when you get caught out you play the victim that is pretty sad man?
I hope dennmarko never lost to much with this liar? and they he has learned a lesson to trust nobody lol That is not true people can be trusted but people like the op make it difficult
