1) Can you explain how came that 661000 tokens were bought for $440000, which is roughtly 1 PRP for $0,66 (pretty much pre-sale price).
* $200K were raised during pre-ico was 1 for $0,65.
* Then $240K was raised at prices $0,8 to $1.
Average should be around $0,75-$0,8. Ok, let's take your 250 PRP bonus into account, that'd shift the average down to $0,75. But no way it is $0,65.
During TGE1, ETH price was around $300, so that's not an explanation. BTC raised, but 12 BTC were raised first day at a price around $5400 or even less if it was during pre-ico.

I feel it's unfair, because my ETHs arrived #2 after the launch on October 12. So I took all the risks of unclear future of ICO, but instead of early-bird reward I got ~2500 PRP less than average investor would get with same amount of ETH. My price was $0,785 for PRP.

2) How long can you keep the development of project going with funds currently raised? Taking possible ICO bubble crash into account, 2018H1 might not be the best time to start TGE2. What if you feel it's needed to postpone it to later, than how later can you make it?

3) About bounty. ~2% of TGE1 tokens were intended for bounty program. Since you raised about 10% of your initial plan, does that mean that bounty distribution will be around 20% of what was purchased? If it's so, than as PRP hit exchanges, people may start selling their free tokens, which may crash the price down to 0.
