Reposting my comment from another thread about DeFi. There's clear innovation and utility in that space and it would be a shame to kill it all over the worst crypto has to offer.
"There are financial primitives that cannot exist in traditional finance that I'd call pretty novel. For example flash loans allow uncollateralized loans for millions of dollars[0].
