I really could not feel disappointed if he would not be successful with... whatever he is developing.
Although I have no idea of what he tries to create, just the name KimDotcom already has that touch of bad carma.
And this guy making his next business about bitcoin, that is something I would rather not want to read in the newspaper tomorrow.
Exactly right, he's poison. His involvement in Bitcoin to the general public would just be another example of a criminal element like Silk Road loving the new crime money. Every time someone like him preaches for Bitcoin it's just another nail in the coffin of public perception. About half of my friends already think I'm nuts for having any of my money tied up in "crime dollars" as one friend put it. Another one of my friends asked how much I have invested in the Medellín Cartel (because I support Bitcoin).
GTFO, he has a list of tens if not 100s of millions of people interested in file sharing, and he is building a decentralized file sharing service that allows content uploaders to monetize that content. Imagine piratebay + storj + bitcoin. Download anything for $0.05.
It will be ENORMOUS.
You don't know that. I would think that there are already too many players in the file sharing game, plus he doesn't have the best reputation, since a lot of people also lost legitimate files when MegaUpload got seized.
Now since this is decentralized, seizing the service might not be possible anymore, but I just doubt that end-users are really looking for another file sharing service, decentralized or not (most end-users don't care).
