F2p gems per month ?

Hi so we just had the gilded jade attack of nian event which was amazing to collect gems and other items. I wonder how many gems does an active f2p player collect a month without such an event? i think this was probably an exception or are other events similarly positive? Since im a new player im trying to understand how much gems ill be saving in the future. ive put all my gems into VIP so far im at vip6 and 130k gems right now in less than a month of playing but i doubt its possible to do that the following months ?
