I've delayed writing this because I needed extra proof, but recently I've seen more projects do the same thing that projects like RFC did.
Think of projects like Remus, Agawa, and even Mutumbo they've done crazy moves recently, and apparently people that used the onchain feature on Bitget even got more ROI because they were in earlier.
Dude, I don't even have an idea about these projects that you've mentioned. If you have followed them and invest on them too early, congrats to you. You're one of the kind and someone who's still able to early invest into them.
A personal example is Dark, and although I didn't get a lot, it has listed on many top CEX, and if I sell for the current price, that would be more than 8000% ROI and I actually wish I got more. But sure I'd be trying this again, to confirm my theory, finger crossed.
A 100% of ROI is already enough and thinking of 8000% and even more, you're still thinking of more. There's a big lesson that someone who sees that much ROI and still wanting more, you'll see a drop of it soon if you'll not cash it out. If your theory is right then again, congratulations, you're on your way to riches but make sure to take profits.
