Default bonding curve:
Initial price: 1 MINA per 100,000 tokens (0.00001 MINA per token), or 10_000 / 10 9
Curve K: 1 MINA per 100,000 tokens (0.00001 MINA per token), or 10_000 / 10 9 MINA
Owner fee: 10% in 0.001 % units(10 1000 = 10_000)
Price formula: price = startPrice + curveK totalSupply
Example:
If supply is 200,000 tokens, price = 1 MINA + 1 MINA 200_000 / 100_000 = 3 MINA per 100,000 tokens
or per token in MINA/1e9
10000 + 10000 200_000 / 100_000 = 30000 per token,
or 30_000 * 100_000 = 3_000_000_000, or 3 MINA per 100,000 tokens

To calculate the max supply for the given price for 100,000 tokens:
price = startPrice + curveK totalSupply
price - startPrice = curveK totalSupply
(price - startPrice) / curveK = totalSupply
(3 MINA - 1 MINA) / 1 MINA = 2 100_000 = 200_000 tokens
(30_000 - 10_000) / 10_000 = 2 100_000 = 200_000 tokens
or, in 1e9 units:
(30_000 - 10_000) 1e9 100_000 / 10_000 = 200_000_000_000_000, or to avoid overflow,
(30_000 - 10_000) 1e9 / 10_000 100_000 = 200_000_000_000_000
