As always, lit article brother.
Use Metamask or a hardwarewallet - these were safe, apparently; even "during the hack".
And I have heard that this Mew url only was "http" and not "https" but people did not "mind" haha.
Btw. I really do not like the situation of eth. This 'possible hardfork' definitely should not happen - I think it is called EIP 999 or something like that, not sure. But this is just not good for eth.
In regards to the batchoverflow exploit: Simply awful, negligent... Security is so essential (especially in crypto).
Cheers!
