How can someone send ETH before the time of the opening? Some one sent ETH 5-8 mins before 16.00 GMT and took all the bonuses....
Where did you find this?
He didn't, his clock is broken.
The truth is in the blockchain, as always:
https://etherscan.io/txs?a=0x49edf201c1e139282643d5e7c6fb0c7219ad1db7&p=57As you see, only 1 ETH was sent a few hours before the ICO, probably as a test transaction.
Then, exactly at 16:00 GMT the transactions started to come in.
So, nothing suspicous.
