A friend told me he lended on bitfinex during the fork and got everything back.
I even asked in the comments but bitfinex somehow didn't answer.
Can someone confirm how bitfinex handled this, please ?
Nonetheless i think the correct way would be different and "force" the borrower to buy the ETH(postfork) + ETC to give it back.
And prolly rename the chains to ETHHF and ETC so there is no confusion. But noone could ever know that there would be two forks, but hey thats why i would wait as an exchange in such case.
I agree with that. I have quite a few Ethereum lent on the Poloniex before the hard fork, and the ETC disappeared.
