Asking $1000 for one roll is ridicoulousy high in my opinion. After all these chips are assembled in China. Not to mention the poor conditions and the low wages in these chinese factories. It wouldn't surprise me that the private keys have been compromised by an unscrupulpous worker. Integrity breaches already happened, even with well establish coin maker like Smoothie and others...
Also, IMHO, the market is over saturated with the recent group buy which took place when BTC reached the stratosphere...
I would't even buy them at face value...
What are all those accusations based on?
I would DEFINITELY take your ''professional'' advice on that..
