so IDO will probably only be an option for Defi projects and the like. projects that are less concerned with government regulation will use IDOs, and the remainder will continue to use IEOs as a means of raising initial funding.
DEFI's crowdsale can be launched on IEO or IDO. That depends on the agreement that has already made with the partnership. Mostly of IDOs were running on the swap service platform like 1inch, uniswap, or another swap service.
Both were having the same chance to be a successful project. There's no a lot of differences between IEO and IDO.
People should understand the difference between IEO and IDO, because IEO's are mainly conducted by the top exchanges like Binance, Huobi, FTT etc. Now IDO's are conducted small swap, an exchange which they are conducting to raise the funds both in ETH blockchain and BSC platform, even the fundraising seems to be very low like 1 million dollars.
Don't mix the whole thing up, top exchanges aren't the only ones conducting IEO projects which leaves room for scammers to operate, I still remember few IEO projects from p2pb2b exchange and exmarket, we know that such projects will never raise funds successfully because such exchanges don't care about reputation
