What are the advantages of doing a BCO compared to an ICO/IEO/DCO?
One major difference is that there is
no pre-mint.
For ICO/IEO/DCO all the tokens are created upfront then sold in large volumes to early investors.
In a BCO everyone has to buy from the Curve directly, in some cases even the project itself.
As the price raise up quickly along with tokens minted out the contract, it also
favors much more early investors.Also the liquidity is inside the contract, not in the pocket of the token issuer.
Thus, it makes it
more transparent and ensure permanent liquidity for the token in a decentralized manner.
No more needs for market makers doing wash trading all day on centralized exchanges to ensure liquidity. (Case of ICO/IEO)
It is closer from a DCO (DEX Coin offering) but without the pre-mint and with a tailor-made AMM favoring much more early investors.
seems there is two crowdfunding method born now
in this thread there is a BCO and i read in below article there is a BRO
This BRO seems to be an interesting concept, looking like a SAFT (Standard Agreement for Future Tokens).
Similar to what Polkadot did with DOT but via a smart contract directly instead of paper.
Would eventually worth considering to mixing both for more fairness (BCRO?)
Thanks for sharing

I think there's no unique feature it has over another, still the same thing.
It does have major difference as the way tokens are emitted and the resulting P&L for investors have influence the future success of the project.
Bitcoin mining makes its distribution somehow fair: early miners received a lot, supply decreases overtime, driving its price up progressively.
The BCO contract reproduces this mechanism because every new token minted out of it is exponentially more expensive than the one before.
So if you buy from BCO contract earlier, you get the token at a better price.
Liquidity is also going inside the contract directly, (like a DEX's liquidity pool) so it is more transparent and fair (backs the token price with actual liquidity).
