The provided code seems to be written in C or C++ but it contains some syntax errors. Here is the corrected version of the code:

```c
int crypto(int num) {
if (num % 2 == 0)
return num / 2;
else if (num % 2 != 0)
return num - 1;
}

int currency(int num) {
int bit = 0;
while (num 0) {
num = crypto(num);
bit += 1;
}
return bit;
}
```

Now, let's analyze the code:

1. The `crypto` function takes an integer as input. If the number is even, it returns half of the number. If the number is odd, it subtracts one from the number and returns the result.

2. The `currency` function also takes an integer as input. It initializes a counter `bit` to 0. Then it enters a loop that continues until `num` is greater than 0. In each iteration of the loop, it calls the `crypto` function with `num` as the argument and assigns the result back to `num`. It also increments `bit` by 1 in each iteration. Finally, it returns the value of `bit`.

Now, let's predict the output for `currency(213)`:

1. `213` is odd, so `crypto(213)` returns `212`.

2. `212` is even, so `crypto(212)` returns `106`.

3. `106` is even, so `crypto(106)` returns `53`.

4. `53` is odd, so `crypto(53)` returns `52`.

5. This process continues until `num` becomes `0`.

6. The `bit` counter increments by `1` in each iteration of the loop.

So, the output of `currency(213)` will be the number of times the loop in the `currency` function executes until `num` becomes `0`. This is essentially the number of steps it takes to reduce `213` to `0` using the rules defined in the `crypto` function.
