Injective protocol isn't bad at all, I will like to add this to my other DeFi coins like Polkadot and Avalanche, the team behind the project are damn serious and ready to lift the project higher, about the ROI I'm sure this project is capable and will keep rising, still it's better to do your own research
DOT and AVAX were native coins and both were trading at the so many major exchange sites. INJ was a native dex coin and it can be the same like BNB but it already created to be the utility usage for the INJ dex users.
You must know the differences between the native platform and dex.
INJ is not the same as DOT and AVAX. that's a cross chain dex platform dude.
