It's not enough if you just change Nitros to Microlitecoins, in the past if the user had already deposited and his balance converted to Nitros, are there had changes also? because I have still seen note 1 Nitro = 100 photons on the withdrawing tab? so what is the purpose?.
Nitros and microlitecoins are the same thing. No conversion took place. It was simply a name change to make sure users understood they were wagering in litecoin.https://en.wikipedia.org/wiki/Litecoin
In the picture, you can see Photons same as microlitecoins or μŁ, this means when conversion (1 Nitro = 100 photons) the signup user got 50 Nitros (50x100=5000 photons or 5000 μŁ), if you understand what I mean when the user has deposited before, it possible they have the wrong conversion right now. maybe it's not applicable for users which got 50 Nitros from the sign-up bonus, this was affected only for the people was deposited litecoin before.
