Why are we multiplying minimumUsd with 1e18? Since the msg.value is already converted to USD, we should compare it with USD on the right side. |

@Dibu2002 For comparing it to the left side of the value (msg.value) we need to convert the 50 USD to Wei. |

Yeah, I understood it now. Thanks. What was confusing was that the value returned by getConversionRate was already divided by 1e18, which I thought had removed all zeroes to convert to USD, but since we are entering ethAmount in Wei, 18 zeroes are still left to be removed, that's the reason minimumUsd is multiplied by 1e18. |
