I don't quite get the explanation of the op regarding IDO, I thought the full meaning of IDO is Initial Dex Offering (IDO) Which is usually carried out in most of the dex we have in the market, most project with dex like polkastar are hosting ido on their network to support and encourage the community IDO are gaining popularity because they are less stressful and cost effective than ieo, many projects now opt for IDO which is not a bad idea at all.
I completely agree, I can see that this new fundraising trend is gaining much popularity slowly, since most projects are looking for a cheap and easy way to launch their project, I think IDO appears to be the most easiest of them all, ieo and ico already fading away, project hardly conduct ico this days, IDO is the best way for project to raise funds, many projects dex like pancakeswap, Dodoswap, uniswap, 1inch and several others has made it much easier to carry out ODO without stress.
