You get plat by two ways; purchase it with real money or get it through trading.

Credits are not useless; the only things you need to spend plat on are weapon, companion and frame slots. Other than that, you can either buy it with credits or get it as an alert reward.

I may have omitted some details, but that's the basic gist of it.
