This is the hardest achievement in the game, however it's not that difficult since you only need 10 platinums out of 32 levels. Please be aware that this game is VERY random with the bounces and smashes, so you will most likely have to replay a mission multiple times before you get the result you want. I am posting my videos below mostly for an idea of when to explode and the path I took, so there's no way to exactly copy them. I found that some are a lot more difficult than others. I could consistently get close-ish to the platinum scores, but had to retry quite a few times sometimes to hit it. I'm sure these paths can be improved, but as this is the first post for this achievement, I'll leave it up unless something better comes along.
GENERAL TIPS*There are 6 floating coins per level. 3 bronze, 2 silver, and 1 gold. If you collect all 3 bronzes, then both silvers, then the gold (in that order), you will get a Grand Slam bonus at the end which will earn you $5 million. If you collect them out of order (eg, bronze, silver, bronze, bronze, silver, gold), then you will earn a smash and grab bonus, which is worth $2.5 million. For most levels, the key to platinum is to get this Grand Slam bonus of $5 million and this is where my videos come in.
* You will get 1 smashbreaker after 4-10 crashes, and you can pick up extras mostly next to the coins. You press
to activate it. You don't need all of these, but they help get to where you need to go. I often had 1 extra. The general idea of this is to explode when cars are around you for max score, or if not, then use it to get to where you need to go. NOTE: If you are still holding
when you do your first smashbreaker, you will fly far into the air. If you are not, or holding brake
, you will jump less. Different jumps suit different areas, so adjust accordingly (you should be able to tell in my video what I used by the height of the jump).
* Timing is everything. I try to time my videos so I smashed at the point that cars are crossing a path, so often you will see me use smashbreaker fast to get to a certain point. This is often me trying to get to a medal before traffic comes to me so I can smash and get to the next point (this is better for score).
I don't have videos for every level, but there are more than 10, so you should have enough to go by.

I would suggest if you are having trouble, just move on to the next one.
