Update:Dev: "Cryptodev team told me that they will have the new version of Unify at the end of the week! No swap will be needed. Everyone simply will need to update their wallets and that's it

"
New wallet should be released by the end of this week! It will have "Dark Gravity Wave" system integrated. This will reduce difficulty fluctuations, improved blockchain security & much more! 
Another common difficulty readjustment algorithm is the Dark Gravity Wave, as originally used in Darkcoin, which combines multiple exponential and simple moving averages to smooth difficulty readjustments and mitigate against exploits in the Kimoto Gravity Well.
According to the developer[1], "[DGW] uses multiple exponential moving averages and a simple moving average to smoothly adjust the difficulty. This implementation is far more simplistic and better suited to adjust difficulty than KGW and also fixes all known exploits."
