No users founds were affected, project is still very early so it's quite easy to get enough hash power to attack it but attacker couldn't liquidate the assets due to lack of liquidity on exchanges anyway. If there was enough liquidity he wouldn't be able to perform the 51% attack in the first place because likely the hash power required to perform a 51% attack would be impossible to get as you can't use asics and the total hash power would be much higher.

This project is very underrated IMO
