There are a very few projects on hive that are trying to build and Leo is one of them. I agree that a few things they built didn't work but atleast they're trying and this is an important part. Some of things they have done are -
- Microblogging experience on blockchain
- Easy onboarding for web 2 users through
- Lite account
- DeX
- Dash collaboration
Its your decision to vote them or not but I think that they deserve your and community support so that they continue to build and bring Value to hive. Here very few projects are working and Leo is on top. Thanks.
