SBD has around 8.7M supply for a 8.6$ price = 74M
HBD has 24.8M supply at 1.25$ price = 31M
Coingecko is showing some odd numbers for supply, the numbers above are from the blockexplorers.
To get to 74M market cap we will need to print around 50M more HBD, for a 1$ price, or some lower number for higher HBD price.
