This isn't true of Protocol Labs. They have already shipped IPFS, which is already in substantial use. Filecoin's testnet is live now, they have not shipped mainnet yet, but it's pretty imminent at this point. There are certainly some ICO scams out there, but I do not believe Filecoin was one of them. I still think $200m was too much, too soon. However, they didn't issue the tokens to themselves under the table. They issued a SAFT agreement for tokens to accredited investors in the United States, abiding by SEC regulations. They allocated 10 percent to investors, 15 percent to themselves, 5 percent to the Filecoin foundation, and 70 percent for Filecoin miners. That was all part of the upfront ICO.
It could turn out to be a flop, but the only people that would lose would be accredited investors who, according to regulations, should know better. I would say Filecoin has at least as good of a chance of succeeding as any ordinary VC investment.
