[ANSWERED]About gold halve.

So, some weeks ago we had all in-game gold halved. I just have a couple of questions related to it:

1- Will it happen again?

2- If so, how often does it usually happen?

Thanks in advance :) just planning on how to manage my own in-game gold :)

Possibly.
Usually once a year, in the first months of the year. We always give at least a month for people to prepare.
