As for today, nothing changed. Bountyhunters.io still ask for Keystore file when one will claim bounty tokens.
There was an announcement from the team that they will provide an alternative way to withdraw this tokens but as for now, nothing happened.
I keep asking myself how many people filled their private keys, mnemonics, keystore files already and when this all wallets will be hacked?
As you can see, we actually dont ask anyone to provide key from their main wallets (and we've placed a warning against it in our dashboard). You always can create new keys exactly to work with Bounty Hunters and provide ones, if you dont trust our wallet implementation.
BTW next week we will add MetaMask support for those who not enough familiar how to deal with crypto and keys.
As an evidence that we don't hide ourselves (unlike scammers do), we've made a short video explanation with our CEO, Mikhail Savchenko:
