The cartesi team has planned everything so what will IEO do later at the right time might become a cartesi waiting for halving to start IEO and now focus more on developing their own products so that they are more familiar with the community.
Whatever happens later after IEO is about to start, we will see how developments and which exchanges will be chosen.
When cartesi can create at least a good MVP and it can try to apply for the IEO on a good exchange site. As far as I know if binance will try to choose an IEO based on how good the prototype that has already made by the team. The reputation of the team matters a lot too. We will see that what will be the exchange that will become an IEO place for cartesi
I think that MVP Cartesi is already good but it's just still in the future development. If MVP is loved by many of its communities then the possibility of applying for IEO in a large stock exchange will be granted as well because I see Cartesi growing more and more there are already many projects that partner with cartesi meaning many support their MVP.
