due to it have reach the 2000BTC, I think project team should close the ICO at once to protect investers, don't make it become the 2nd wave.
Why would they? And how would that be fair to someone who has decided to 'wait and see' where this leads, only to know the ICO is closed. The goal of the ICO for the founding team is to raise as much as they can. The 2000 BTC was a minimum, which is easily crossed. ++1. Time will show that this will be just another scamcoin.
