Sometimes it is hard to ignore the FUD, I was never in this for the short term though so I had already committed to losing my BTC if this project didn't go anywhere.
My concern is with the functionality of the the network, I really would like to know if the devs have considered any of the problems and what their plan of action would be. With only ~4 million BRX available and many of them on the exchange I think the confirmation time to maturity will cause a problem with PoS moving the chain quickly enough for the network to be viable.
Your math is way off. We have ~ 6M BRX with less than 1M on Bittrex. Staking is fine. What we need is pool setup for miners so the POW blocks can help move the chain as intended.
