BTC wroth $10010 exchanged to BCC (when rate was say 400$); scam exposed and exit from devs give 1 BCC = $150; $10010 ends up with 66.73 BCC; which value then crashed to say $25 ($7 at lowest in the week). Ends up with $1668. Ouch that's a huge loss for those gullible enough to put their eggs on it. But huge gain for the BCC devs since they've got the BTC.
You have this a little wrong. BitConnect converted people's USD valued loans to BCC at a rate of $363 per BCC, so a $10010 loan ended up being converted to around just 27 BCC. The BCC then fell to say $25, meaning the $10k loan was now worth just $675. Over a 90% loss.
