is there a minimum set to hold on your account before recieving fees for holding KCS , because i buyed some very expenive one's , almost 10 $ , but did not recieve any amount for 3 days now?
Same here (five days in fact). Sounds like they are working on it :

Looks like they are backed up on payments, I received payouts for Jan 16, today, the 19th whereas yesterday I'd been paid up until Jan 15. I'm assuming they'll eventually catch up.
yes, it happened before didn't get any payouts on 11-15 January, got them all on 16th. They have gone from 200k to 2M members in a month so i guess the servers are tiny bit overloaded
