We are considering raising the BRO per BTC to 5000 for anyone that was sitting on the fence. This would also effect buyers that bought below 5000 (there were not many), they would get a bump up to 5000 also.
With a working prototype, this isn't going to be necessary. Let this ICO end at these prices and then come back and start at 2000 BRO/BTC. People will buy then, once they learn you have a functioning platform.
Lowering the price now isn't going to drive sales in the short term. People aren't buying because they don't know about the working tech, not because BRO is too expensive.
