2. our coin was hurt much by cbuchner/pttx private GPU miner(now we have open source GPU, it was released just more than week ago)
how exactly did the open source GPU miner help the coin's valuation? right, it didn't.
It didn't because of misinformation spread across the board that you have this magic miner and it is unfair for others to mine BBR, so it never got traction. Check Poloniex trollbox to see how much they just talk down BBR because of a "private miner". Now trollboxes are obviously not the place one needs to get legitimate info, but the coin would have done much better had you made the miner public, come out and helped users discuss BBR more in the forums etc.
Your latest post shows you have no interest in helping this coin. Yet you claim you hold a large amount as a long term investment. It is quite unbelievable all around what has happened to this coin's valuation.
Not that any of this is your responsibility though. It isn't your coin, and you owe the people trying to develop it nothing. You can and should do what you want and whatever makes you the most money.
How convenient for you to say this. Save your ensuing "it's a fact" drivel that would probably ensue.
