The crowdsale is capped at USD 600,000.
Six hundred thousand USD? Am I reading that right? WOW!
Payment only in BTC? Probably just a coincidence that the block payout on BTC will halving soon.
Caveat emptor.
We had to put a cap, to be honest, the project is going full steam ahead with only ~54 btc raised up till now.
