1. Why are almost all bounties released today DeFi projects?
2. Most of these projects have no information about team
As you have seen over the past time the market has embraced the DeFi trend, which is why new projects are constantly appearing. So what are these new projects for, there will be projects that do the right thing, but there are also projects conceived to deceive people into this market. This is easy to understand because those are projects that are intending to deceive you, if not clear, they can ask them to deposit a stablecoin (if you can convince BM).
3. Majority of them are rushed, you can judge merely looking at website domain and designs
4. There are some that based on Uniswap wannabes
I see the activities of those projects going in the form of 'build a project and fomo quickly'. And of course the best way is to find an easy tool to reach many people like the list on uniswap, or simply with the 'name project' + DeFi.
