51% wouldn't be hard when the difficulty is usually floating around minimum (0.00024414)
I did have a small miner dedicated to IFC for a while, but I ended up needing it for something else. It was more to keep transactions moving rather than to secure the network (which would need significant hash power, and ideally more than one miner)
Cryptopia seems to be on a cull of 'problem' coins at the moment, so I wouldn't be surprised if it gets delisted
Delisting their top traded coin with LTC is not very good move
I'm Brazilian, my pronouncement sucks, but come on!
Response from Cryptopia team
Thanks for contacting Cryptopia.
Currently our admins are investigating transaction issues with this wallet, as such it has been put into maintenance. Once this status has been lifted transactions will continue to process as normal. Unfortunately we do not have an ETA at this point in time as the investigation is still underway. Your patience in the meantime is very much appreciated.
I'd recommend keeping an eye on our Coin Info page at
https://www.cryptopia.co.nz/CoinInfo/?coin=IFC to be kept up to date with the status of this wallet. It is also a good idea to have a look at this page before you deposit into your Cryptopia account, so you can be aware of any potential delays in receiving your coin in advance.
Other:
The IFC wallet is in maintenance while we investigate a potential issue, unfortunately I can't give you a certain ETA on when we will bring a wallet back online, because this is variable based on what we find in an ongoing investigation, and what is required to resolve it.
Further, there may be a number of factors completely outside our control - ie wallet updates from the coin developer, blockchain and connection issues.
It will survive me thinks.
