What do you mean "did nothing"? They were the first to figure out what was going on and shut down deposits and withdrawals immediately thereafter. They immediately reached out to the Monacoin developers and told them about the issue.
you mean livecoin was the first to figure out they just got double spend attacked and lost funds? i imagine they were.
what would you expect the coin developers to do about it?
Imagine if exchanges accepted zero-confirmation transactions in Bitcoin and then began blaming Core developers because customers managed to double spend attack them. This is the same thing.
This is a disingenuous comparison by the very nature of how cryptocurrency works. Its of course not nearly the same thing.
hmmm, could you explain how they are so different? these are both proof of work protocols. relying on insufficient proof of work = services could suffer double spends.
isn't this why exchanges require a minimum number of confirmations? seems like livecoin didn't require enough confirmations and then allowed the attackers to withdraw before the deposits were double spent. right?
