yeah, project Defi and ico in 2017 is almost the same today many Defi project that generates a lot of profit, but all can be temporary, not being able to walk in a long time is probably just hype will last 1-2 years all Defi program will have flaws and its advantage if the bitcoin prices down will affect the price of coins Defi I would not be surprised if the project Defi will be short enough hype.
