Blockchains are useful for things other than cryptocurrencies. And it's not a conflict of interest to say you don't think blockchains should be used for currencies, much like it's not a conflict of interest for the inventor of dynamite to say he doesn't think dynamite should be used to blow people up. (Google "Nobel Prize".)
