Bourgist had mentioned before the event ended, to not grind presents for conversion, since it was an easy event to grind

If the conversion rate was higher, the economy of the game would be broken and there would be many of millionaires in the game, with the possibility of there being billionaires

hence why the conversion rate is low

If anyone else wants to add on to what I have just mentioned, feel free to

Honestly, this is not a scam. You should've listened to Bourgist or youtube videos that say don't grind for presents.
