The tokens you receive are equivalent to a value, for example: 6.5 wld equivalent to $15, but if the currency is rising, you will receive fewer wld or vice versa you will receive more wld

Any expert in this world? I see that wld has dropped a lot and also that they are giving less and less wld, before it gave 25 wld as a welcome, then it gave 20, and yesterday a friend registered and they gave him 16wld!!! Is this good? Since I suppose that there will be less and less wld or someone explain it to me #WorldCoin. #wld $BTC
