Black Market: Always Bet on Bronze?

So, here's the thing:

I never played the black market gatcha game that much, because odds are pretty good that you'll get stuff you don't need. I'd spin through tons of silver crates and usually just end up with yet another Typhon or something. Or maybe a pilot I'd never use. All the time, I just ignored the bronze crates because, well, nothing in them was particularly shiny or interesting. But then I eventually ran out of green crack, and while considering buying some more, I noticed that usual little $1.99 for 8000 keys deal in the market. So, I shrugged and decided to see what I'd get for 8000 keys worth of bronze crates.

After mass-opening tons of the things, I finally realized the true power of the bronze crates: everything in them is useful. It's always silver, gold, a bit of platinum, power cells, and (perhaps best of all) more keys. As you keep winning keys, you keep opening more and more bronze crates, getting more and more basic resources and still more keys. On average (And after selling the inevitable Dreadnaught A24 parts you win), that $2 key purchase will end you up with several million silver, about 1500 gold, several hundred platinum , and several thousands of power cells. It's probably the best deal in the game for maintaining all your basic upgrade resources.

Anyone else playing it like this?
