Name 2 or 3 cryptonotes who have done this and the currency trading has resumed outside of those listing within the Monero article?
XDN, BCN, and DashCoin all updated their code after the Monero article.
It is a simple matter to merge a few lines of bug fix into the code. If the original dev returns he can fix his repo, otherwise the community can move on without him (if people care to bother).
No one should ever send their coins to some unknown stranger on this forum whether said unknown stranger claims to be doing a 'coin swap' or not.
If you want to do a legit swap, then find a very trusted member to collect the old coins, with the condition that they will be returned if the coin swap is not successful.
Do Not trivialize the matter as it is not so "simple". First dev must notify Pool Ops and miners, which has not been done. Next scan of network chain must take place to ensure no exploit have happen, then patch can be applied, now source must be issued so that all pool ops, miners and other are in concensus.
None of this has taken place by the BXC dev or community.
Thus I myself acting as only person within the BXC community has taken suitable action to correct the Major Bug issue.
