This was not something the team could have foreseen. The decision to give a 24-hour grace period was good: with BTC and WAVES so volatile, just the rise in the markets would have triggered the end of the crowdsale, only to have the risk of the total dropping back to $2.7 million or so not long afterwards. No one could know that a massive whale would come in like that.
Frankly it's a difficult situation to negotiate. If the whale had come in at $2.99m, then that last $1m would have to have been accepted anyway.
So far the team has proven highly professional and competent. And this was an unintended consequence of doing the right thing. So it's worth being more constructive about any criticism.
