What will happen if the hard cap is reached? Token sale is over? Or thier will be another crowdsale for those late comers who didnt get any chance to buy the token.
Nope, this is the only sale. Tokens not sold burned and all that. It is slower now, but Ethereum network is so congested that is not surprising.
You can always buy them later in exchanges. It will end 72 hours after a certain amount is sold... details on the page
