The topic of solvency has been up more than once now. We can't look into their internal fiscal books but we can look at the blockchain. What I propose is that we as a community come together and collect this information. It is known that they are mining like crazy and that BTC refunds are paid out of those operations.
Everyone who has been refunded in BTC now or since the beginning please help the community out by filling out this short survey:
I am a KNCminer customer and I am behind this survey. The sole purpose is to trace how much BTC KNCminer AB is holding.
This thread is currently so spread out that I would prefer further conversation regarding this survey and address collection at a forum dedicated to KNC( http://www.hackmyminer.com/forum/index.php?forum=7)
