Not to burst the bubble but yeah, I think this is personal for him. That's why he sell his stash because they are moving to a new Solana-based NewChain. So he could have thinking, good riddance to the project and then dump everything.
And after that it's over for him, and most likely he might think that MakerDAO did make a big mistake. However, I'm not sure why the move though, perhaps they don't like what they are seeing on Ethereum or just having problems with his chain or something.
As for the development of MakerDAO, there's something on it but whether he takes it personally or not. It's on him and if this is like showing that it's his personal revenge through selling/dumping then that's it.
well then I guess his main motive was money, but i could see the fact that maybe he dumps it just because the token itself serves no purpose for him now that its moving over to solana and he didn't really interested into participating in that blockchain.
i'm sure he has his own motive and i'm also sure that he has foreseen the future dumping of this token, surely if he dumping all his token the other would be attracted to do the same.
but we'll see. considering the fact that many in twitter perceived this coin to be overvalued, I guess there will be corrections.
It was all for money and that was him and his passion before that he turned into money was just part of the process. That's all the motivation ever since and whatever the issues that he's facing together with these other projects that he probably has supported before, if he sell then that's it and don't make something from it as if there's a drama.
