Bro, some people wait till last days of crowdsale just to reduce risk and volatility of eth, btc to usd price to be clear so they know what exactly they are investing, so im sure investments will increase much quickly near end.
Propy team has been working towards ticking all the box so as to make their project raise more fund and give it more needed exposure. To be sincere I thought by now the ICO would have been sold out becuase the team is very solid for me all you need from a team you find it in them
It will probably sell more. Now there are so many ICOs so it's hard to chose and gain attention.
