Smell something fishy here. Its really obvious that this coin is running a shady project. Why the software asking for the private key? It should only kept by the owner.
And not all is interested on mining because some are in tropical areas, which is not highly recommended. It is better if you run an airdrop or bounty instead. ICO is priority to spread the information about this project.
We are not asking for your private key at all. Please read everything correctly. To mine KIWI, you send solutions to the blockchain - this costs gas to do so, so you need to pay for that. The mining software signs the transaction on your behalf, otherwise you will have to sign each transaction manually.
And for those that are not interested in mining that is fine, we will have other methods for people to earn KIWI later on when we build our products.
As for running an ICO - no thanks, they are mostly scams and we do not agree at all how they currently run. The ICO companies issue tokens at very high prices, collect the ETH and also give themselves tokens. As for just giving away the token in Airdrop, that is also just another scam, where the token owner keeps a percentage for themselves, then airdrops tokens hoping that you will trade them and give their own held tokens value.
A mineable token is much fairer than those models. We ourselves have to mine to get KIWI and so we are much more incentivised to ensure that the KIWI grows in value.
So, please tell me what is fishy here.. and just to be clear, you can see the contract code, you can look at the code for the mining software - there are several different options, or you could write your own mining software if you want.
