I think the main hype for "fast" investment in crypto have passed a long time ago (during ico and ieo). Now in defi there's some hype but still it's not the same like 3 years ago.
Basically every hype that occurs in crypto is not the same, be it ICO, IEO or DeFi, because every year the market conditions are always different in terms of demand and supply, so that differences will always occur every year.
