Thank you ever for the answer
But I find there is not enough advertising for the project on the internet
There is no minimum contributions of Ether, but for this Pre-ICO (now until 23:59 GMT, 14th September), to earn 10% bonus, minimum of 1 Ether is required.
On the marketing side, we're improving on this. We shall post the bounty program as well later.
Thanks for your support.
From the website itself when you click on contribute:
"The minimum contribution during pre ICO is 1 ETH or its equivalent in BTC and FRD. Any lower than 1 ETH contribution by user during the pre ICO we will return back."
That is no longer valid. Any contributions during PreICO shall get 10% extra.
