Their ratio is 1 ETH=6000 treon tokens,and bonus is 30%,so you can calculate

Well, this is just 1st stage pre-ICO, sale is doing very well

If the sale continues like this, they will surely get enough funds until 27th July.
I've heard the sale is going quite well - the project seems to have taken off and I'm glad to hear it.
The flow of the sale is really important to determine a possible outcome of the project. If the project sale is going slow then, well, that's not good, but if the sale is going to well, then we might have a case of a pump and the an eventual dump. People need to be aware of that.
Clearly, there are always two possible sales trends, but it is important that sales flows in the positive direction, regardless of the potential dump.
