A coin toss did not determine Iowa.
First the tosses pick county delegates, not state delegates county delegates are not nearly as valuable.
In addition:
The state party doesn’t track all of the coin flips, but following anecdotal reports of Clinton’s improbable luck on Monday night, Lau disclosed that it was Sanders who fared better in the games of chance that were reported through the party’s official mobile app. The Vermont senator won six of those seven coin flips--a fact that underlines how incomplete the available data remains, and the likelihood that a full accounting of all the coin flips on Monday night would yield a more even result than initial reports suggested.

So
- The coin tosses are not that important.
- We don’t know how many there were, but it appears likely to be more than a dozen.
- We don’t know who benefitted more.
- Coin tosses are a longstanding part of the Iowa Caucus, and no more ridiculous than anything else related to the process.
So there is no real evidence of a conspiracy and/or unusual lucky streak at play.
