they have best skills in hacking technique.but unfortunately they use it to criminal action and harmed every body.if they joined in dev team they could use their skill to build their own project about security.
i am definitly agree with you mate,they could use their skills in good purpose.build their own project about security would be best project in cryptomarket.no one harmed and they earn money from it.
