Well, that's unfortunate and certainly an unprofessional way to deal with it... add the lack of information till the last minute and there really is a lot to be concerned about but the most people will agree that it's still an attractive ICO.
To compensate that, we actually have the smart contract published:
https://github.com/sonm-io/ico-contracts/blob/master/contracts/ICO.solHas anyone with some solidity knowledge looked at it? Does it appear watertight? After all, that's the beauty of the Ethereum platform, the smart contract is there for all to see even if the team doesn't provide any comments at present.
Another question I'm pondering is how would investing with bitcoin work. If it's an Ethereum smart contract then how does that get triggered by a BTC transaction? Does it get converted automatically or something? This would imply that we're better of buying ETH at better rates than whatever the rate is at the moment of the transaction.
