Isn't increasing deposit confirmations an option, even something super high like 12-24 hours (not sure how many blocks that would be, but it would be a long time to sustain a block withholding attack and therefore prohibitively expensive)


Also, has anyone heard if/when the bittrex wallet will re-open?

Yeah and MONA has been off since last Thursday. Both coins were hit by 51% attacks where the attacker did double spends on exchanges.

You would think they could just increase the confirmations for deposits on those coins (even if it is something ridiculous like 24 hours).

At the very least you think they could provide some sort of update to the community on how long they expect them to be down.


The worst part is, while I can find other exchanges for btg, mona appears almost impossible to exchange unless you live in Korea or Japan and can validate identity with an exchange there. I guess I'll have to stop mining it and eat the loss on what I have.
