This is bad for potential future ICO projects. They need more cybersecurity and hire network security experts to work with their companies, which will limit the loss of large projects.
They just need to have better passwords !
Seriously, I don't trust ICOs from companies that give just one ETH/BTC address for your deposit. Some are giving one address per contributor. This is much more secure ! And you can track your transfers. This should be a useful information to display on the ICO schedule websites.
