Talking for charity is good to hear even though our money has been stolen, but I don't think they can afford to hack our wallet, bro, unless a copy of your wallet key is given to them,
It's still no good because the money are now in the hands of the hacker and not those who really deserved it. In case we accidentally leaked our private keys then we should act quick and transfer the amount into a fresh wallet and then totally abandon the old one as hacker may hack it anytime if they haven't started yet.
Now that Ethereum is suppose to get cheaper to use, will people instead of maybe giving a few people a copy of your key,
Cheaper in terms of what? Fees? I think this isn't confirmed yet but we will observe it, these coming days if there's really an improvement in terms of fees. Private keys should be kept in private, that is why its name is private keys. I think those people who gave it are newbies or out of their mind if they aren't really a newbie after all.
