I mean if the ingot can transfer into something useful...or more value item....I would love to deposit my money or Invest my money on it.....but unfortunately....this event is so bad...literally bad...

I think you misunderstand the event...it's not like you can keep claiming the 1000 coupon once you buy the 5000 ingot package...its more like 1 time 1000 coupon and then keep claimed the following reward everyday...It's more like a * that you won't get back what you supposed to get and the value of 5000 ingot is diminished by following daily reward you can get back.
