Preserve is an open decentralized search engine that rewards their users for searching. But now there is a daily limit for search reward. Only you will get reward for first 32 search, per searching you will get 0.25 token that means 8 tokens daily. That's not huge but I enjoy this search engine. Google never pay us for searching but this decentralized platform appreciate our searching. I use it instead of Google. I have added it at my mobile home screen and here searching is comfortable like Google.

The token has already listed on coinmarketcap and their total token supply is 1 billion. So I think this platform will be great. I always love blockchain technology and also love blockchain based platform.
Hope in near future we will get more useful platform like this.
