Is the first-purchase bonus (2x gold) worth it in Dragonfire?

Like many mobile games, Dragonfire shows a first-purchase bonus: your first gold pack purchase pays out double gold (2x), once.

What that means in practice:

• It's a one-time bonus, valid only once (on the first eligible purchase)
• So the gold-per-euro ratio of that first purchase is the best you'll ever see

Neutral advice: if — and only if — you had already decided to spend, that's mechanically the most "efficient" purchase in gold per euro. But don't trigger a purchase just for the bonus: the 2x is an incentive. No spending plan = no purchase. The bonus doesn't expire as long as you haven't used it.
