So you can earn diamonds on crypto.com by fulfilling daily missions. Those missions consist of checking the missions page, trading $20 worth of crypto in a single transaction and trading crypto in total worth $500. 

The easiest way to finish all these missions of course is to do 2 swaps between currencies. Swap $250 of Bitcoin to Nano and then the Nano back to Bitcoin for example.

Doing all these nets you a total of 66 diamonds. Thats enough to open 2 boxes (25 diamonds per box). Each box contains a random amount of CRO, ranging between 0.3 CRO (Bronze box) to 2000+ CRO (Platinum box). Most common seems to be 0.7 CRO (Silver box).

So was it worth it? Well yes and no. Of course free crypto is always amazing especially when you can get crypto worth currently 1270$ (2000 CRO).

And doing these missions would take you about a minute to do in total. But one thing that people (including myself) often forget is the maker/taker fee that gets put upon these exchanges (0.4% for under $25,000).

So, in order to break even of swapping $500 dollars, we would need to get CRO worth of at least 2$, which at this point equals to 3.14 CRO. That means even getting always gold boxes (1 CRO), you wouldn't break even.

So in conclusion, I think these missions are a very nice touch and a good idea for people that are actively trading to get a little gambling fun in there from time to time. But doing these missions with the purpose of making profit? Not really.
