It doesnt have Monero's legacy and has adopted all the three years improvements that has been applied on Monero by various hard forks.

I think Dev should have more actions to change this diff because many people will not want to mine this coin with this high diff .
This price is being down and it seems many investors sold this coin during the past.
The latest codes to solve this issue are being tested on testnet, some adjustments will be needed but basically that works fine now. As you may all know, this will require a harkfork to implement so we will be able to activate it only after making sure Cryptopia updates it and it would be a few days after finalizing the fork. We targets next Monday as the soonest possible day for the fork begin, meanwhile, we don't pour hashrate to network to make diff getting lower, as you know, the attackers are just waiting for it.
