Hello I wanted to participate in the BlockDag coin presale today.

h t t p s : / / blockdag . network /

I first loaded my TrustWallet with $150 worth of ethereum.

Then I followed the instructions from their website to connect my TrustWallet to their network and I've transferred the ethereum to their address.
 
I have the transaction record that shows the transfer from my wallet to their address.

The question now is how do I get the BlockDag coins ? From their website it says:

How Will Participants Receive Their Tokens After Contributing to The Presale, And What Is The Estimated Timeline for Token Distribution?



Participants can receive their tokens by connecting their wallets to BDAG. The tokens will be airdropped to your account once the presale is completed and the claiming is active.
The estimated timeline for token distribution depends upon the project’s development progress.

Once the presale is over and I connect my wallet to BDAG, how will it know how much I've bought and how many coins to transfer to my wallet ?

Have I just been scammed $150 worth of Ethereum ?
