My only concern is centralizatin of this coin. It seems, only few people are accumulating it. This + PR problem with private miner + holding the price low artificially can result into breaking backbone of this coin. Some other coin will copy BBR, will make better distribution and PR and chance is lost... I hope whales of this coin will do something about it soon.
This is my concern too. With the slew of recent coins that died by one holder dumping a massive sum, my trust in someone else's word has run very thin.
A public GPU miner needs to become a thing or this coin will end up looking awfully similar to BCN - innovative but not worth investing in because of the incredible disparity in coins owned.
