The recent appearance of Defi project massively on services sections, Have kept me off balance. But I need to understand the future of Defi projects, and why stablecoin "Dai" is doing better than bitcoin and Ethereum on the long run? The disadvantages of DEFI project is an added thank you. 
For the future, the DeFi project is still unclear whether it will be strong or it will self-destruct over time, because the foundation on which the DeFi project is based is still not really solid and strong for this year.
