This has been proven and everyone already knows that all projects that use Defi are definitely interesting, but there are also many fake projects that try to use Defi to make a profit by copying someone else's team image and it will really annoy everyone who wants to invest in it. But I am sure with Defi, all projects that will use the Defi system are really serious in working to give the best and prove to all investors to remain committed so that the project reaches its target and will be successful.
Fake projects and scams and then weak code that cyber criminals can exploit resulting to many investors losing huge amount of money in Defi.
So I would say that it still has some big risk and even though the market is still growing in billions, there could also be investors losing millions in a single hack, not good. Everyone needs to be very careful as well, we might see the Defi bubble and it could crash hard. So don't be greedy, if you think you have profited already then take it and don't want till everything goes down.
