3.1. Crowdsale Price
Taking into account the decimals and the rate set by the developers, if any token value is allocated for the crowdsale the investors will receive for every 1 ETC = 10.000.000 token which is the total supply of UNITS token.
Developers should set a different rate otherwise the maximum collected fund will be 1 ETC.
3.2. Sale Availability
In order for the investors to buy tokens the address 0x0 should be set with a certain amount of tokens to be sold, however 0x0 address is set with zero tokens.
The crowdsale won't work.
3.3. Token Transfer to Address 0x0.
Accidentally transferred to zero address tokens may be sold.
3.4. Extra checking.
Severity: minor observation
Extra checking in 90 and 100 lines. SafeMath library checks it anyway.
Those lines may be deleted.
The contract developers should consider the issues described above. the contract cannot be deployed.
